Fraser Health Statement on Creutzfeldt-Jakob Disease
June 14, 2013
Dr. Paul Van Buynder, Chief Medical Health Officer has released the
following statement to clarify reports about suspect cases of “human mad cow
disease” in the Lower Mainland:
“I am concerned to see reports this evening in social and traditional media
related to our investigation into a small number of possible cases of
Creutzfeldt-Jakob disease (CJD). Media have reported that these cases are
connected to Bovine Spongiform Encephalopathy – more commonly known as mad cow
disease.
Fraser Health has investigated six possible cases of CJD over the past
year. After a case review today we can say that one person has CJD and two
others are very likely to have it. The other three cases are very unlikely to
have CJD.
I want to be clear there is absolutely no evidence that these three
confirmed or probable cases are linked to food consumption.
CJD is a neurological disorder reported an average of about 30 times a year
in Canada. There are a handful of cases reported in B.C. each year and we expect
around 2 cases in the Fraser region. While three in this time frame is one or
two more than I expect, it is within statistical likelihood.
There is no outbreak and I want to reassure residents of the lower mainland
that there is no risk to the public or to residents in our facilities.
These are classical cases of CJD. Tests conducted on these patients have
ruled out variant CJD associated with disease in cattle. There has never been a
home grown case of variant CJD in Canada so this is not surprising.
We have a strong public health surveillance system in B.C. and a review of
the cases has not revealed any links between them which would suggest a common
source of any kind. The patients investigated come from a number of different
cities and settings.
Our sympathies are with the families of these cases of severe progressive
disease."

Greetings Dr. Paul Van Buynder et al @ FraserHealth,
Sadly, in the year 2013, we are still going by science that is 3 decades
old, to manage risk factors from the many different strains of the TSE prion
disease.
Dr. Paul Van Buynder et al state ;
> I want to be clear there is absolutely no evidence that these three
confirmed or probable cases are linked to food consumption.
when in reality, you have no clue Sir.
sporadic CJD is not a single strain of the TSE prion sporadic phenotypes
(there are many, and they are mounting).
sporadic CJD has now been linked to atypical BSE, and atypical Scrapie, and
many reputable scientist around the globe are especially concerned with the CWD
of cervids, and it’s different strains, which we now know there are more
strains.
the UKBSEnvCJD only theory is a false myth, and proven to be so.
also, all iatrogenic CJD is, is sporadic CJD until route and source of the
TSE agent is confirmed.
what fuels this madness, and the spread of this disease, are Doctors and
officials that continue to spread this junk science.
you are part of the problem, in my opinion, and I mean no disrespect Sir.
if I still sound angry, I am, 15+ years later.
I have wasted 15 years daily following the science as it emerges with the
TSE prion disease, and documenting it. I hope you take the time to read some of
it.
no need to reply, most never do, but I urge you to educate yourself on this
topic of the TSE prion disease, and cease spreading the false science that
continues to fuel the spread of this TSE prion disease. ...
thank you, kind regards,
terry
layperson ...lost my mom to the hvCJD ‘confirmed’, and I just made a
promise. ...

EFSA Journal 2011 The European Response to BSE: A Success Story
snip...
EFSA and the European Centre for Disease Prevention and Control (ECDC)
recently delivered a scientific opinion on any possible epidemiological or
molecular association between TSEs in animals and humans (EFSA Panel on
Biological Hazards (BIOHAZ) and ECDC, 2011).
*** This opinion confirmed Classical BSE prions as the only TSE agents
demonstrated to be zoonotic so far but the possibility that a small proportion
of human cases so far classified as "sporadic" CJD are of zoonotic origin could
not be excluded.
Moreover, transmission experiments to non-human primates suggest that some
TSE agents in addition to Classical BSE prions in cattle (namely L-type Atypical
BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic
wasting disease (CWD) agents) might have zoonotic potential.

Seven main threats for the future linked to prions
First threat
The TSE road map defining the evolution of European policy for protection
against prion diseases is based on a certain numbers of hypotheses some of which
may turn out to be erroneous. In particular, a form of BSE (called atypical
Bovine Spongiform Encephalopathy), recently identified by systematic testing in
aged cattle without clinical signs, may be the origin of classical BSE and thus
potentially constitute a reservoir, which may be impossible to eradicate if a
sporadic origin is confirmed.
***Also, a link is suspected between atypical BSE and some apparently
sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases
constitute an unforeseen first threat that could sharply modify the European
approach to prion diseases.
Second threat

Rural and Regional Affairs and Transport References Committee
The possible impacts and consequences for public health, trade and
agriculture of the Government's decision to relax import restrictions on beef
Final report June 2010
2.65 At its hearing on 14 May 2010, the committee heard evidence from Dr
Alan Fahey who has recently submitted a thesis on the clinical neuropsychiatric,
epidemiological and diagnostic features of Creutzfeldt-Jakob disease.48 Dr Fahey
told the committee of his concerns regarding the lengthy incubation period for
transmissible spongiform encephalopathies, the inadequacy of current tests and
the limited nature of our current understanding of this group of
diseases.49
2.66 Dr Fahey also told the committee that in the last two years a link has
been established between forms of atypical CJD and atypical BSE.
*** Dr Fahey said that: They now believe that those atypical BSEs overseas are in fact causing sporadic Creutzfeldt-Jakob disease. They were not sure if it was due to mad sheep disease or a different form. If you look in the textbooks it looks like this is just arising by itself. But in my research I have a summary of a document which states that there has never been any proof that sporadic Creutzfeldt-Jakob disease has arisen de novo-has arisen of itself. There is no proof of that. The recent research is that in fact it is due to atypical forms of mad cow disease which have been found across Europe, have been found in America and have been found in Asia. These atypical forms of mad cow disease typically have even longer incubation periods than the classical mad cow disease.50

Atypical BSE in Cattle
To date the OIE/WAHO assumes that the human and animal health standards set
out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE
which include the H-type and L-type atypical forms. This assumption is
scientifically not completely justified and accumulating evidence suggests that
this may in fact not be the case. Molecular characterization and the spatial
distribution pattern of histopathologic lesions and immunohistochemistry (IHC)
signals are used to identify and characterize atypical BSE. Both the L-type and
H-type atypical cases display significant differences in the conformation and
spatial accumulation of the disease associated prion protein (PrPSc) in brains
of afflicted cattle. Transmission studies in bovine transgenic and wild type
mouse models support that the atypical BSE types might be unique strains because
they have different incubation times and lesion profiles when compared to C-type
BSE.
When L-type BSE was inoculated into ovine transgenic mice and Syrian
hamster the resulting molecular fingerprint had changed, either in the first or
a subsequent passage, from L-type into C-type BSE. In addition, non-human
primates are specifically susceptible for atypical BSE as demonstrated by an
approximately 50% shortened incubation time for L-type BSE as compared to
C-type. Considering the current scientific information available, it cannot be
assumed that these different BSE types pose the same human health risks as
C-type BSE or that these risks are mitigated by the same protective
measures.
This study will contribute to a correct definition of specified risk
material (SRM) in atypical BSE. The incumbent of this position will develop new
and transfer existing, ultra-sensitive methods for the detection of atypical BSE
in tissue of experimentally infected cattle.
*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.
The chances of a person or domestic animal contracting CWD are “extremely
remote,” Richards said. The possibility can’t be ruled out, however. “One could
look at it like a game of chance,” he explained. “The odds (of infection)
increase over time because of repeated exposure. That’s one of the downsides of
having CWD in free-ranging herds: We’ve got this infectious agent out there that
we can never say never to in terms of (infecting) people and domestic
livestock.”
*** The discovery of previously unrecognized prion diseases in both humans
and animals (i.e., Nor98 in small ruminants) demonstrates that the range of
prion diseases might be wider than expected and raises crucial questions about
the epidemiology and strain properties of these new forms. We are investigating
this latter issue by molecular and biological comparison of VPSPr, GSS and
Nor98.
VARIABLY PROTEASE-SENSITVE PRIONOPATHY IS TRANSMISSIBLE ...price of prion

OR-10: Variably protease-sensitive prionopathy is transmissible in bank
voles
Romolo Nonno,1 Michele Di Bari,1 Laura Pirisinu,1 Claudia D’Agostino,1
Stefano Marcon,1 Geraldina Riccardi,1 Gabriele Vaccari,1 Piero Parchi,2 Wenquan
Zou,3 Pierluigi Gambetti,3 Umberto Agrimi1 1Istituto Superiore di Sanità; Rome,
Italy; 2Dipartimento di Scienze Neurologiche, Università di Bologna; Bologna,
Italy; 3Case Western Reserve University; Cleveland, OH USA
Background. Variably protease-sensitive prionopathy (VPSPr) is a recently
described “sporadic”neurodegenerative disease involving prion protein
aggregation, which has clinical similarities with non-Alzheimer dementias, such
as fronto-temporal dementia. Currently, 30 cases of VPSPr have been reported in
Europe and USA, of which 19 cases were homozygous for valine at codon 129 of the
prion protein (VV), 8 were MV and 3 were MM. A distinctive feature of VPSPr is
the electrophoretic pattern of PrPSc after digestion with proteinase K (PK).
After PK-treatment, PrP from VPSPr forms a ladder-like electrophoretic pattern
similar to that described in GSS cases. The clinical and pathological features
of VPSPr raised the question of the correct classification of VPSPr among prion
diseases or other forms of neurodegenerative disorders. Here we report
preliminary data on the transmissibility and pathological features of VPSPr
cases in bank voles.
Materials and Methods. Seven VPSPr cases were inoculated in two genetic
lines of bank voles, carrying either methionine or isoleucine at codon 109 of
the prion protein (named BvM109 and BvI109, respectively). Among the VPSPr cases
selected, 2 were VV at PrP codon 129, 3 were MV and 2 were MM. Clinical
diagnosis in voles was confirmed by brain pathological assessment and western
blot for PK-resistant PrPSc (PrPres) with mAbs SAF32, SAF84, 12B2 and 9A2.
Results. To date, 2 VPSPr cases (1 MV and 1 MM) gave positive transmission
in BvM109. Overall, 3 voles were positive with survival time between 290 and 588
d post inoculation (d.p.i.). All positive voles accumulated PrPres in the form
of the typical PrP27–30, which was indistinguishable to that previously observed
in BvM109 inoculated with sCJDMM1 cases.
In BvI109, 3 VPSPr cases (2 VV and 1 MM) showed positive transmission until
now. Overall, 5 voles were positive with survival time between 281 and 596
d.p.i.. In contrast to what observed in BvM109, all BvI109 showed a GSS-like
PrPSc electrophoretic pattern, characterized by low molecular weight PrPres.
These PrPres fragments were positive with mAb 9A2 and 12B2, while being negative
with SAF32 and SAF84, suggesting that they are cleaved at both the C-terminus
and the N-terminus. Second passages are in progress from these first successful
transmissions.
Conclusions. Preliminary results from transmission studies in bank voles
strongly support the notion that VPSPr is a transmissible prion disease.
Interestingly, VPSPr undergoes divergent evolution in the two genetic lines of
voles, with sCJD-like features in BvM109 and GSS-like properties in BvI109.
The discovery of previously unrecognized prion diseases in both humans and
animals (i.e., Nor98 in small ruminants) demonstrates that the range of prion
diseases might be wider than expected and raises crucial questions about the
epidemiology and strain properties of these new forms. We are investigating this
latter issue by molecular and biological comparison of VPSPr, GSS and Nor98.

Press reports indicate that increased surveillance is catching what
otherwise would have been unreported findings of atypical scrapie in sheep. In
2009, five new cases have been reported in Quebec, Ontario, Alberta, and
Saskatchewan. With the exception of Quebec, all cases have been diagnosed as
being the atypical form found in older animals. Canada encourages producers to
join its voluntary surveillance program in order to gain scrapie-free status.
The World Animal Health will not classify Canada as scrapie-free until no new
cases are reported for seven years. The Canadian Sheep Federation is calling on
the government to fund a wider surveillance program in order to establish the
level of prevalence prior to setting an eradication date. Besides long-term
testing, industry is calling for a compensation program for farmers who report
unusual deaths in their flocks.

Potential future zoonoses
Scrapie is endemic in many countries around the world, yet there is no
evidence to suggest that it is pathogenic for humans. The intense investigations
of ruminant TSEs that followed the BSE epidemic have resulted in the
identification of several distinct animal prion diseases, atypical or Nor98
scrapie in sheep and H-type and L-type BSE in cattle.32 Moreover, BSE is
experimentally transmissible to sheep and there are concerns that if BSE were to
have infected the national flock in the UK its presence might be masked by
endemic scrapie, but it might retain its pathogenicity for humans.33,34 Another
concern, particularly for the North American countries, is the spread of chronic
wasting disease in farmed and free-ranging deer and elk.35 There is no known
epidemiological link between any of these animal prion diseases and human
disease, but there are active efforts to try to quantify strain-related species
barriers between the diseases known to be a risk (BSE/ vCJD), those thought not
to represent a risk (scrapie) and those for which data is lacking (atypical
scrapie, H- and L-type BSE and BSE in sheep).36 In assessing whether or not
human prion diseases might have an animal origin, it is important to have a
proper understanding of the clinicopathological heterogeneity of the sporadic
human prion diseases, because it is against this backdrop that any new acquired
forms of the disease will be seen and from which it will need to be
distinguished.
Sporadic CJD and variably protease-sensitive prionopathy
Sporadic CJD is the most commonly occurring human prion disease; it occurs
world-wide and it has long been known to be clinically and pathologically
heterogeneous. The molecular basis for this heterogeneity is currently thought
to reside in a combination of the PRNP codon 129 polymorphic status of the
patient (MM, MV, or VV) and the type (type 1 or type 2) of the
protease-resistant component of PrPSc determined by protease K digestion and
Western blotting (termed PrPres).37,38 The original sCJD sub-classification
system of Parchi et al. that recognized six sCJD subtypes (MM1/MV1, MM2c, MM2t,
MV2,VV2 and VV1) has had to be modified to accommodate the growing number of
cases recognized to contain both type 1 and type 2 PrPres in different or
sometimes the same regions of the brain.39,40 Moreover, intensive surveillance
and investigation of forms of human prion disease that lack PRNP mutation and
known risk factors has identified another sporadic human prion disease, termed
protease-sensitive prionopathy (VPSPr).41While intensively investigated, the
etiology and diversity of the sporadic human prion diseases remain poorly
understood.

There is also a potentially important practical corollary to the idea of
prion-like spread, which may affect future stem cell therapies for
neurodegenerative diseases. Presumably therapeutic stem cell-derived neurons
would be equally susceptible to “infection” (with misfolded protein aggregates)
as the patient’s own cells, unless steps were taken to prevent this,55 the most
obvious of which would be to prevent expression of the gene product that can be
converted to a pathological prion-like isoform.The suggestion that a prion-like
mechanism of spread of molecular pathology underlies diseases as diverse as
Alzheimer’s disease and Parkinson’s disease has led some researchers to explore
whether the molecular pathology of these diseases is transmissible in an
experimental setting56–58 and to suggest that perhaps some cases of these more
common neurodegenerative illnesses might, like CJD, be acquired.58,59

MOLECULAR BASIS OF HUMAN PRION DISEASES
Molecular strain typing Molecular strain typing in the form of classifying
the mobility and glycoform ratio of protease-resistant prion protein byWestern
blotting is a remarkably useful adjunct to neuropathological assessment during
the post-mortem diagnosis of human prion diseases (Fig. 1). The glycoform ratio
difference between vCJD and all forms of sCJD is a remarkably robust phenomenon,
although the mechanism underlying it remains obscure. All cases of vCJD examined
show type 2B PrPres, irrespective of brain region assayed and the PrPres type is
also found in lymphoreticular tissues, albeit with presumably tissue-specific
minor modification of mobility and an accentuation of the glycoform ratio.
Similarly sCJD cases are characterized by a narrow range of glycoform ratios,
distinct from vCJD, and the presence of either type 1 or type 2 PrPres (type 1A
and type 2A).The PrPres types found in the brain in iCJD and kuru resemble those
found in sCJD (type 1A and type 2A), from which they were presumably derived.
Individual cases of gCJD, GSS and FFI usually have type 1 or type 2 PrPres, but
with a glycoform ratio in which the non-glycosylated component is
under-represented (which we have termed A/B). However, this is not always true
and a broad spectrum of glycoform ratios can be found in genetic prion diseases.
Moreover, some cases of GSS are characterized by an approximately 8 kDa (N- and
C-terminally truncated) PrPres fragment, and some cases of FFI have little
detectable PrPres at all. Despite the diagnostic utility, a simple one-to-one
correspondence between PrPres type and disease phenotype (and by implication to
agent strain) seems unlikely in principle and is complicated by the facts.
First, the choice of analyzing only that fraction of PrPSc which survives a
particular concentration of protease may seem arbitrary. Second, the
interpretation of a molecular population variable, such as glycosylation site
occupancy, as conforming to two or three discrete types, could be seen as
simplistic. Lastly, protease digestion may be considered to be a somewhat blunt
instrument to distinguish secondary and higherorder conformational differences
in PrPSc. Even when genotype (mutations and polymorphisms) is taken into
account, three major types (1, 2, 8 kDa) and three wild-type genotypes (MM,MV
and VV) provide insufficient molecular variation to account for all the
phenotypic variations observed. For example, two forms of sCJD share methione
homozygosity and type 2A PrPres but one form closely resembles FFI (without the
causative mutation) and the other is CJD-like.8 Two more substantial problems,
which may point toward a more subtle and perhaps informative approach to PrPSc
analysis, are discussed below. The co-occurrence of PrPres types 1 and 2 Once
controversial, the idea that PrPSc in individual cases might be composed of
mixtures (or different types co-occurring) is now well recognized and
accepted.40,70 There are probably two phenomena at play here. One is the finding
of different predominant types in individual samples from different parts of the
brain or more rarely approximately equal amounts of type 1A and type 2A in the
same sCJD brain samples.The other is the observation made using antibodies that
specifically recognize type 1 or type 2 PrPres, that a minority type always
accompanies a majority type in sCJD and vCJD, albeit at sub-detectable levels
when conventional antibodies are used.71–75 The former issue is more tractable
and a consensus is beginning to emerge that when multiple brain sampling and
sensitive co-detection is performed on cohorts of sCJD cases, a plateau is
reached at between 30–40% of cases showing co-occurrence. Our own data examining
four regions (temporal cortex, parietal cortex, occipital cortex and thalamus)
instead of frontal cortex only, shows a rise in detected co-occurrence from 3%
to 24% of cases.76 Interestingly, only very rarely did this re-analysis involve
a change in the predominant type found in the brain overall. Parchi et al. have
offered a revised version of their 1999 sporadic CJD classification system that
adds mixed type to the original “pure” types and have shown that the most common
of these 12 sCJD subtypes can be recognized on histological grounds, without
reference to biochemical analysis.39,40,77 It will be interesting to see in the
fullness of time whether this additional complexity reflects a more refined
series of discrete clinicopathological phenotypes or whether it is indicative of
a spectrum of phenotypes depending on the spacio-temporal accumulation of PrPSc
types set against the patient genotype.78
Variably protease-sensitive prionopathy The phenotypic complexity of the
sporadic forms of human prion disease has increased with the report of a new
sporadic human prion disease, termed variably proteasesensitive prionopathy
(VPSPr) that is distinct from previously recognized sub-types of sCJD.41,79
There are no mutations in the open reading frame of PRNP. The patients have no
known risk factors for the disease, but the disease is most common in theVV
genotype, as opposed to sCJD, which is most common in the MM genotype. The
neuropathology involves medium-sized vacuolation and characteristic
microplaques. Durations of illness can be very long and this coupled with
symptoms that do not conform well to CJD have prompted speculation that the
condition may be under-ascertained. The most interesting aspect of the disease
from a biochemical perspective is that although PrPSc is abundantly present in
the brain, PrPres is difficult to detect because of its sensitivity to
proteolysis and because what remains after proteinase K (PK) digestion is both
C- and N-terminally cleaved by PK digestion and seen as a faint 8 kDa band on
Western blots (Fig. 2). The degree of protease resistance is reported to reflect
the codon 129 genotype, withVV being least resistant andMM being most resistant,
despite having the same 8 kDa PrPres fragment predominating.79We have identified
two cases of VPSPr prospectively in the UK80,81 and recently completed a
retrospective review for such cases confirming many of the original observations
by Gambetti and colleagues.41,79 Our work has shown that some areas of the VPSPr
brain contain PrPres similar in appearance to that found in sCJD and conversely
that some cases of sCJD have a very minor PrPres band similar to the 8 kDa
PrPres band that typifies VPSPr.82
snip...
The biochemical basis of the strain phenomenon The results of transmission
of individual samples from single examples of the six different Parchi et al.39
sCJD subtypes (MM1/MV1, VV1, MM2c, MV2, VV2) into humanized transgenic mice
suggest the existence of four distinct sCJD agents, termed M1, M2, V1 and V2,
and a fifth strain corresponding to MM2t or sporadic fatal insomnia.99,100
Interestingly, when we performed formally analogous experiments in the cell-free
PMCA reaction, similar results were obtained: The PrPres type of the seed was
conserved in the PMCA product and the efficiency of conversion appeared to be
determined by compatibility at codon 129 of PRNP.101 The behavior of the seeds
from heterozygous patients were particularly interesting, in that MV1 sCJD seeds
selectively amplified in MM substrate producing type 1 PrPres and MV2 sCJD seeds
selectively amplified in VV substrate producing type 2 PrPres (Fig. 6). These
results reinforce the association between methionine at codon 129 and the
production of type 1 PrPres and valine at codon 129 and the production of type 2
PrPres.
EMERGING RISKS
Zoonotic disease BSE is the only animal prion strain with demonstrated
pathogenicity for humans.While it is tempting to suggest that scrapie might
represent the animal reservoir that results in some cases of sCJD, there is no
epidemiological evidence to support this hypothesis. The pathogenicity of new or
newly described animal prion diseases for humans is unclear and this is
particularly true for H- and L-type BSE, atypical scrapie and for chronic
wasting disease (CWD), all of which are probably consumed. Human susceptibility
has been modeled by attempted transmission to (humanized) transgenic mice with
sometimes conflicting results, depending on the transgenic model used and
depending upon whether central or peripheral tissues are examined.102–106 We
have attempted to establish whether PMCA can model the molecular component of
these hypothetical cross-species transmission events.107 The existing data
correspond well with the established facts. First, PrPSc in vCJD brain samples
amplifies most efficiently in humanized mouse MM substrate, less efficiently in
MV substrate and not at all in VV. Cattle BSE PrPres is less efficient than
vCJD, but shows the same substrate genotypic preference. Sheep scrapie fails to
amplify detectably in any of the three substrates; however, sheep BSE PrPres
does amplify, again with a codon 129 preference for methionine (Fig. 7). We are
currently extending this approach to encompass atypical scrapie, H- and L-type
BSE and CWD using human rather than humanized PMCA substrates.
Secondary infection
In the same way that animal reservoirs cannot be completely excluded as
causes of individual sCJD cases, neither can other environmental sources, such
as medical procedures. The known routes of iatrogenic CJD acquisition are
historically growth hormone therapy, dura mater grafting, corneal grafting and
certain highly specialized neurosurgical procedures. The secondary transmission
of vCJD by blood transfusion and experimental evidence showing the efficiency of
the transfusion of viable blood cells between scrapie and BSE-infected and naive
sheep have prompted a reappraisal of transfusion-transmitted CJD, including
consideration being given to the possibility of prion blood testing or
filtration.25,26,108,109
Blood transfusion is the original and most extensively used cellular
therapy, but we may be on the threshold of a new era of cellular therapies based
on embryonic stem cell and induced pluripotent stem cell technologies. Although
the potential for stem cell therapy-mediated prion transmission might be judged
remote, this was also considered to be the case for transfusion transmission of
CJD before 2004.
snip...
SUMMARY AND PERSPECTIVE
While the prospect of a major epidemic of vCJD in the UK and elsewhere
seems to be receding, there remain a series of uncertainties surrounding the
eventual numbers of individuals that will suffer from this devastating
condition.The issues include the effects of genotype on susceptibility and the
possible existence of substantial numbers of asymptomatic infected individuals
that may pose risks of onward transmission. sCJD remains the most frequently
occurring human prion disease and arguably the least well understood. Other
idiopathic forms of human prion disease (such as VPSPr), characterized by
protease-sensitive forms of the prion protein, also exist and their true
prevalence may be hard to ascertain. The possible risks from newly described
animal prion diseases and from emerging cellular therapies are currently poorly
quantified. On a more theoretic level the prion hypothesis has provided a
unifying conceptual framework for TSE research and provided a paradigm to
interrogate the similarities and differences between the diverse
neurodegenerative conditions involving prion-like mechanisms of molecular
pathology.

Alzheimer’s disease and Transmissible Spongiform Encephalopathy prion
disease, Iatrogenic, what if ?
Background
Alzheimer’s disease and Transmissible Spongiform Encephalopathy disease
have both been around a long time, and was discovered in or around the same time
frame, early 1900’s. Both diseases are incurable and debilitating brain disease,
that are in the end, 100% fatal, with the incubation/clinical period of the
Alzheimer’s disease being longer (most of the time) than the TSE prion disease.
Symptoms are very similar, and pathology is very similar.
Methods
Through years of research, as a layperson, of peer review journals,
transmission studies, and observations of loved ones and friends that have died
from both Alzheimer’s and the TSE prion disease i.e. Heidenhain Variant
Creutzfelt Jakob Disease CJD.
Results
I propose that Alzheimer’s is a TSE disease of low dose, slow, and long
incubation disease, and that Alzheimer’s is Transmissible, and is a threat to
the public via the many Iatrogenic routes and sources. It was said long ago that
the only thing that disputes this, is Alzheimer’s disease transmissibility, or
the lack of. The likelihood of many victims of Alzheimer’s disease from the many
different Iatrogenic routes and modes of transmission as with the TSE prion
disease.
Conclusions
There should be a Global Congressional Science round table event set up
immediately to address these concerns from the many potential routes and sources
of the TSE prion disease, including Alzheimer’s disease, and a emergency global
doctrine put into effect to help combat the spread of Alzheimer’s disease via
the medical, surgical, dental, tissue, and blood arena’s. All human and animal
TSE prion disease, including Alzheimer’s should be made reportable in every
state, and Internationally, WITH NO age restrictions. Until a proven method of
decontamination and autoclaving is proven, and put forth in use universally, in
all hospitals and medical, surgical arena’s, or the TSE prion agent will
continue to spread. IF we wait until science and corporate politicians wait
until politics lets science _prove_ this once and for all, and set forth
regulations there from, we will all be exposed to the TSE Prion agents, if that
has not happened already.

Abstract
Ample justification exists on clinical, pathologic, and biologic grounds
for considering a similar pathogenesis for AD and the spongiform virus
encephalopathies. However, the crux of the comparison rests squarely on results
of attempts to transmit AD to experimental animals, and these results have not
as yet validated a common etiology. Investigations of the biologic similarities
between AD and the spongiform virus encephalopathies proceed in several
laboratories, and our own observation of inoculated animals will be continued in
the hope that incubation periods for AD may be even longer than those of CJD.

TRANSMISSION OF ALZHEIMER-TYPE PLAQUES TO PRIMATES
1. CMO will wish to be aware that a meeting was held at DH yesterday, 4
January, to discuss the above findings. It was chaired by Professor Murray
(Chairman of the MRC Co-ordinating Committee on Research in the Spongiform
Encephalopathies in Man), and attended by relevant experts in the fields of
Neurology, Neuropathology, molecular biology, amyloid biochemistry, and the
spongiform encephalopathies, and by representatives of the MRC and AFRC. 2.
Briefly, the meeting agreed that:
i) Dr Ridley et als findings of experimental induction of p amyloid in
primates were valid, interesting and a significant advance in the understanding
of neurodegenerative disorders;
ii) there were no immediate implications for the public health, and no
further safeguards were thought to be necessary at present; and
iii) additional research was desirable, both epidemiological and at the
molecular level. Possible avenues are being followed up by DH and the MRC, but
the details will require further discussion. 93/01.05/4.1

TRANSMISSION OF ALZHEIMER TYPE PLAQUES TO PRIMATES
1. Thank you for showing me Diana Dunstan's letter. I am glad that MRC have
recognized the public sensitivity of these findings and intend to report them in
their proper context. This hopefully will avoid misunderstanding and possible
distortion by the media to portray the results as having more greater
significance than the findings so far justify.
2. Using a highly unusual route of transmission (intra-cerebral injection)
the researchers have demonstrated the transmission of a pathological process
from two cases one of severe Alzheimer's disease the other of
Gerstmann-Straussler disease to marmosets. However they have not demonstrated
the transmission of either clinical condition as the "animals were behaving
normally when killed'. As the report emphasizes the unanswered question is
whether the disease condition would have revealed itself if the marmosets had
lived longer. They are planning further research to see if the conditions, as
opposed to the partial pathological process, is transmissible. What are the
implications for public health?
3. The route of transmission is very specific and in the natural state of
things highly unusual. However it could be argued that the results reveal a
potential risk, in that brain tissue from these two patients has been shown to
transmit a pathological process. Should therefore brain tissue from such cases
be regarded as potentially infective? Pathologists, morticians, neuro surgeons
and those assisting at neuro surgical procedures and others coming into contact
with "raw" human brain tissue could in theory be at risk. However, on a priori
grounds given the highly specific route of transmission in these experiments
that risk must be negligible if the usual precautions for handling brain tissue
are observed.
92/11.4/1-1 BSE101/1 0137
4. The other dimension to consider is the public reaction. To some extent
the GSS case demonstrates little more than the transmission of BSE to a pig by
intra-cerebral injection. If other prion diseases can be transmitted in this way
it is little surprise that some pathological findings observed in GSS were also
transmissible to a marmoset. But the transmission of features of Alzheimer's
pathology is a different matter, given the much greater frequency of this
disease and raises the unanswered question whether some cases are the result of
a transmissible prion. The only tenable public line will be that "more research
is required" before that hypothesis could be evaluated. The possibility on a
transmissible prion remains open. In the meantime MRC needs carefully to
consider the range and sequence of studies needed to follow through from the
preliminary observations in these two cases. Not a particularly comfortable
message, but until we know more about the causation of Alzheimer's disease the
total reassurance is not practical.

Filamentous inclusions made of hyperphosphorylated tau are characteristic
of numerous human neurodegenerative diseases, including Alzheimer’s disease,
tangle-only dementia, Pick disease, argyrophilic grain disease (AGD),
progressive supranuclear palsy, and corticobasal degeneration. In Alzheimer’s
disease and AGD, it has been shown that filamentous tau appears to spread in a
stereotypic manner as the disease progresses. We previously demonstrated that
the injection of brain extracts from human mutant P301S tau-expressing
transgenic mice into the brains of mice transgenic for wild-type human tau (line
ALZ17) resulted in the assembly of wild-type human tau into filaments and the
spreading of tau inclusions from the injection sites to anatomically connected
brain regions. Here we injected brain extracts from humans who had died with
various tauopathies into the hippocampus and cerebral cortex of ALZ17 mice.
Argyrophilic tau inclusions formed in all cases and following the injection of
the corresponding brain extracts, we recapitulated the hallmark lesions of AGD,
PSP and CBD. Similar inclusions also formed after intracerebral injection of
brain homogenates from human tauopathies into nontransgenic mice. Moreover, the
induced formation of tau aggregates could be propagated between mouse brains.
These findings suggest that once tau aggregates have formed in discrete brain
areas, they become self-propagating and spread in a prion-like manner.
snip...
The present work indicates that once small numbers of tau inclusions have
formed in the brain, they may become selfpropagating and spread in a prion-like
manner, independently of other pathogenic mechanisms. What is true of aggregated
human tau may also be the case of other aggregation-prone proteins that cause
human neurodegenerative diseases, including α-synuclein, superoxide dismutase 1,
huntingtin, trans-activator regulatory (TAR) DNA-binding protein 43 (TDP-43),
and Aβ (47). The inhibition of cell-to-cell transmission of pathological
aggregates, for instance by passive immunotherapy, may constitute an effective
mechanism-based therapeutic strategy for most human neurodegenerative diseases.

Abstract
Ample justification exists on clinical, pathologic, and biologic grounds
for considering a similar pathogenesis for AD and the spongiform virus
encephalopathies. However, the crux of the comparison rests squarely on results
of attempts to transmit AD to experimental animals, and these results have not
as yet validated a common etiology. Investigations of the biologic similarities
between AD and the spongiform virus encephalopathies proceed in several
laboratories, and our own observation of inoculated animals will be continued in
the hope that incubation periods for AD may be even longer than those of CJD.

1. CMO will wish to be aware that a meeting was held at DH yesterday, 4
January, to discuss the above findings. It was chaired by Professor Murray
(Chairman of the MRC Co-ordinating Committee on Research in the Spongiform
Encephalopathies in Man), and attended by relevant experts in the fields of
Neurology, Neuropathology, molecular biology, amyloid biochemistry, and the
spongiform encephalopathies, and by representatives of the MRC and AFRC. 2.
Briefly, the meeting agreed that:
i) Dr Ridley et als findings of experimental induction of p amyloid in
primates were valid, interesting and a significant advance in the understanding
of neurodegenerative disorders;
ii) there were no immediate implications for the public health, and no
further safeguards were thought to be necessary at present; and
iii) additional research was desirable, both epidemiological and at the
molecular level. Possible avenues are being followed up by DH and the MRC, but
the details will require further discussion. 93/01.05/4.1

TRANSMISSION OF ALZHEIMER TYPE PLAQUES TO PRIMATES
1. Thank you for showing me Diana Dunstan's letter. I am glad that MRC have
recognized the public sensitivity of these findings and intend to report them in
their proper context. This hopefully will avoid misunderstanding and possible
distortion by the media to portray the results as having more greater
significance than the findings so far justify.
2. Using a highly unusual route of transmission (intra-cerebral injection)
the researchers have demonstrated the transmission of a pathological process
from two cases one of severe Alzheimer's disease the other of
Gerstmann-Straussler disease to marmosets. However they have not demonstrated
the transmission of either clinical condition as the "animals were behaving
normally when killed'. As the report emphasizes the unanswered question is
whether the disease condition would have revealed itself if the marmosets had
lived longer. They are planning further research to see if the conditions, as
opposed to the partial pathological process, is transmissible. What are the
implications for public health?
3. The route of transmission is very specific and in the natural state of
things highly unusual. However it could be argued that the results reveal a
potential risk, in that brain tissue from these two patients has been shown to
transmit a pathological process. Should therefore brain tissue from such cases
be regarded as potentially infective? Pathologists, morticians, neuro surgeons
and those assisting at neuro surgical procedures and others coming into contact
with "raw" human brain tissue could in theory be at risk. However, on a priori
grounds given the highly specific route of transmission in these experiments
that risk must be negligible if the usual precautions for handling brain tissue
are observed.
92/11.4/1-1 BSE101/1 0137
4. The other dimension to consider is the public reaction. To some extent
the GSS case demonstrates little more than the transmission of BSE to a pig by
intra-cerebral injection. If other prion diseases can be transmitted in this way
it is little surprise that some pathological findings observed in GSS were also
transmissible to a marmoset. But the transmission of features of Alzheimer's
pathology is a different matter, given the much greater frequency of this
disease and raises the unanswered question whether some cases are the result of
a transmissible prion. The only tenable public line will be that "more research
is required" before that hypothesis could be evaluated. The possibility on a
transmissible prion remains open. In the meantime MRC needs carefully to
consider the range and sequence of studies needed to follow through from the
preliminary observations in these two cases. Not a particularly comfortable
message, but until we know more about the causation of Alzheimer's disease the
total reassurance is not practical.

Diagnosis and Reporting of Creutzfeldt-Jakob Disease
Terry S. Singeltary, Sr Bacliff, Tex
Since this article does not have an abstract, we have provided the first
150 words of the full text.
KEYWORDS: creutzfeldt-jakob disease, diagnosis. To the Editor: In their
Research Letter, Dr Gibbons and colleagues1 reported that the annual US death
rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These
estimates, however, are based only on reported cases, and do not include
misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would
drastically change these figures. An unknown number of persons with a diagnosis
of Alzheimer disease in fact may have CJD, although only a small number of these
patients receive the postmortem examination necessary to make this diagnosis.
Furthermore, only a few states have made CJD reportable. Human and animal
transmissible spongiform encephalopathies should be reportable nationwide and
internationally.

RE-Monitoring the occurrence of emerging forms of Creutzfeldt-Jakob disease
in the United States
Terry S. Singeltary, retired (medically)
I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment
on the CDC's attempts to monitor the occurrence of emerging forms of CJD.
Asante, Collinge et al [1] have reported that BSE transmission to the
129-methionine genotype can lead to an alternate phenotype that is
indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD
and all human TSEs are not reportable nationally. CJD and all human TSEs must be
made reportable in every state and internationally. I hope that the CDC does not
continue to expect us to still believe that the 85%+ of all CJD cases which are
sporadic are all spontaneous, without route/source. We have many TSEs in the USA
in both animal and man. CWD in deer/elk is spreading rapidly and CWD does
transmit to mink, ferret, cattle, and squirrel monkey by intracerebral
inoculation. With the known incubation periods in other TSEs, oral transmission
studies of CWD may take much longer. Every victim/family of CJD/TSEs should be
asked about route and source of this agent. To prolong this will only spread the
agent and needlessly expose others. In light of the findings of Asante and
Collinge et al, there should be drastic measures to safeguard the medical and
surgical arena from sporadic CJDs and all human TSEs. I only ponder how many
sporadic CJDs in the USA are type 2 PrPSc?

Laying Odds
Are prion diseases more prevalent than we thought?
Researchers and government officials badly underestimated the threat that
mad cow disease posed when it first appeared in Britain. They didn't think
bovine spongiform encephalopathy was a zoonosis-an animal disease that can
sicken people. The 1996 news that BSE could infect humans with a new form of
Creutzfeldt-Jakob disease stunned the world. It also got some biomedical
researchers wondering whether sporadic CJD may really be a manifestation of a
zoonotic sickness. Might it be caused by the ingestion of prions, as variant CJD
is?
Revisiting Sporadic CJD
It's not hard to get Terry Singeltary going. "I have my conspiracy
theories," admitted the 49-year-old Texan.1 Singeltary is probably the nation's
most relentless consumer advocate when it comes to issues in prion diseases. He
has helped families learn about the sickness and coordinated efforts with
support groups such as CJD Voice and the CJD Foundation. He has also connected
with others who are critical of the American way of handling the threat of prion
diseases. Such critics include Consumers Union's Michael Hansen, journalist John
Stauber, and Thomas Pringle, who used to run the voluminous www.madcow. org Web
site. These three lend their expertise to newspaper and magazine stories about
prion diseases, and they usually argue that prions represent more of a threat
than people realize, and that the government has responded poorly to the dangers
because it is more concerned about protecting the beef industry than people's
health.
Singeltary has similar inclinations. ...

Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North
America update October 2009
T. Singeltary
Bacliff, TX, USA
Background:
An update on atypical BSE and other TSE in North America. Please remember,
the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been
documented in North America, along with the typical scrapie's, and atypical
Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these
TSE in different species have been rendered and fed to food producing animals
for humans and animals in North America (TSE in cats and dogs ?), and that the
trading of these TSEs via animals and products via the USA and Canada has been
immense over the years, decades.
Methods:
12 years independent research of available data
Results:
I propose that the current diagnostic criteria for human TSEs only enhances
and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD
only theory in 2009. With all the science to date refuting it, to continue to
validate this old myth, will only spread this TSE agent through a multitude of
potential routes and sources i.e. consumption, medical i.e., surgical, blood,
dental, endoscopy, optical, nutritional supplements, cosmetics etc.
Conclusion:
I would like to submit a review of past CJD surveillance in the USA, and
the urgent need to make all human TSE in the USA a reportable disease, in every
state, of every age group, and to make this mandatory immediately without
further delay. The ramifications of not doing so will only allow this agent to
spread further in the medical, dental, surgical arena's. Restricting the
reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO
age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge,
Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al
and many more, that the world of TSE Transmissible Spongiform Encephalopathy is
far from an exact science, but there is enough proven science to date that this
myth should be put to rest once and for all, and that we move forward with a new
classification for human and animal TSE that would properly identify the
infected species, the source species, and then the route.

Tracking spongiform encephalopathies in North America
Xavier Bosch
My name is Terry S Singeltary Sr, and I live in Bacliff, Texas. I lost my
mom to hvCJD (Heidenhain variant CJD) and have been searching for answers ever
since. What I have found is that we have not been told the truth. CWD in deer
and elk is a small portion of a much bigger problem.
49-year-old Singeltary is one of a number of people who have remained
largely unsatisfied after being told that a close relative died from a rapidly
progressive dementia compatible with spontaneous Creutzfeldt-Jakob disease
(CJD). So he decided to gather hundreds of documents on transmissible spongiform
encephalopathies (TSE) and realised that if Britons could get variant CJD from
bovine spongiform encephalopathy (BSE), Americans might get a similar disorder
from chronic wasting disease (CWD)the relative of mad cow disease seen among
deer and elk in the USA. Although his feverish search did not lead him to the
smoking gun linking CWD to a similar disease in North American people, it did
uncover a largely disappointing situation.
Singeltary was greatly demoralised at the few attempts to monitor the
occurrence of CJD and CWD in the USA. Only a few states have made CJD
reportable. Human and animal TSEs should be reportable nationwide and
internationally, he complained in a letter to the Journal of the American
Medical Association (JAMA 2003; 285: 733). I hope that the CDC does not continue
to expect us to still believe that the 85% plus of all CJD cases which are
sporadic are all spontaneous, without route or source.
Until recently, CWD was thought to be confined to the wild in a small
region in Colorado. But since early 2002, it has been reported in other areas,
including Wisconsin, South Dakota, and the Canadian province of Saskatchewan.
Indeed, the occurrence of CWD in states that were not endemic previously
increased concern about a widespread outbreak and possible transmission to
people and cattle.
To date, experimental studies have proven that the CWD agent can be
transmitted to cattle by intracerebral inoculation and that it can cross the
mucous membranes of the digestive tract to initiate infection in lymphoid tissue
before invasion of the central nervous system. Yet the plausibility of CWD
spreading to people has remained elusive.
Part of the problem seems to stem from the US surveillance system. CJD is
only reported in those areas known to be endemic foci of CWD. Moreover, US
authorities have been criticised for not having performed enough prionic tests
in farm deer and elk.
Although in November last year the US Food and Drug Administration issued a
directive to state public-health and agriculture officials prohibiting material
from CWD-positive animals from being used as an ingredient in feed for any
animal species, epidemiological control and research in the USA has been quite
different from the situation in the UK and Europe regarding BSE.
Getting data on TSEs in the USA from the government is like pulling teeth,
Singeltary argues. You get it when they want you to have it, and only what they
want you to have.
Norman Foster, director of the Cognitive Disorders Clinic at the University
of Michigan (Ann Arbor, MI, USA), says that current surveillance of prion
disease in people in the USA is inadequate to detect whether CWD is occurring in
human beings; adding that, the cases that we know about are reassuring, because
they do not suggest the appearance of a new variant of CJD in the USA or
atypical features in patients that might be exposed to CWD. However, until we
establish a system that identifies and analyses a high proportion of suspected
prion disease cases we will not know for sure. The USA should develop a system
modelled on that established in the UK, he points out.
Ali Samii, a neurologist at Seattle VA Medical Center who recently reported
the cases of three hunterstwo of whom were friendswho died from pathologically
confirmed CJD, says that at present there are insufficient data to claim
transmission of CWD into humans; adding that [only] by asking [the questions of
venison consumption and deer/elk hunting] in every case can we collect suspect
cases and look into the plausibility of transmission further. Samii argues that
by making both doctors and hunters more aware of the possibility of prions
spreading through eating venison, doctors treating hunters with dementia can
consider a possible prion disease, and doctors treating CJD patients will know
to ask whether they ate venison.
CDC spokesman Ermias Belay says that the CDC will not be investigating the
[Samii] cases because there is no evidence that the men ate CWD-infected meat.
He notes that although the likelihood of CWD jumping the species barrier to
infect humans cannot be ruled out 100% and that [we] cannot be 100% sure that
CWD does not exist in humans& the data seeking evidence of CWD transmission
to humans have been very limited.

Re: vCJD in the USA * BSE in U.S.
15 November 1999 Terry S Singeltary, NA
In reading the recent article in the BMJ about the potential BSE tests
being developed in the U.S. and Bart Van Everbroeck reply. It does not surprize
me, that the U.S. has been concealing vCJD. There have been people dying from
CJD, with all the symptoms and pathological findings that resemble U.K. vCJD for
some time. It just seems that when there is one found, they seem to change the
clarical classification of the disease, to fit their agenda. I have several
autopsies, stating kuru type amyloid plaques, one of the victims was 41 years of
age. Also, my Mom died a most hideous death, Heidenhain Variant Creutzfeldt
Jakob disease.
Her symptoms resemble that of all the U.K. vCJD victims. She would jerk so
bad at times, it would take 3 of us to hold her down, while she screamed "God,
what's wrong with me, why can't I stop this." 1st of symptoms to death, 10
weeks, she went blind in the first few weeks. But, then they told me that this
was just another strain of sporadic CJD. They can call it what ever they want,
but I know what I saw, and what she went through. Sporadic, simply means, they
do not know.
My neighbors Mom also died from CJD. She had been taking a nutritional
supplement which contained the following;
vacuum dried bovine BRAIN, bone meal, bovine EYE, veal bone, bovine liver
powder, bovine adrenal, vacuum dried bovine kidney, and vacuum dried porcine
stomach. As I said, this woman taking these nutritional supplements, died from
CJD.
The particular batch of pills that was located, in which she was taking,
was tested. From what I have heard, they came up negative, for the prion
protein. But, in the same breath, they said their testing, may not have been
strong enough to pick up the infectivity. Plus, she had been taking these type
pills for years, so, could it have come from another batch?
CWD is just a small piece of a very big puzzle. I have seen while deer
hunting, deer, squirrels and birds, eating from cattle feed troughs where they
feed cattle, the high protein cattle by products, at least up until Aug. 4,
1997.
So why would it be so hard to believe that this is how they might become
infected with a TSE. Or, even by potentially infected land. It's been well
documented that it could be possible, from scrapie. Cats becoming infected with
a TSE. Have you ever read the ingredients on the labels of cat and dog food?
But, they do not put these tissues from these animals in pharmaceuticals,
cosmetics, nutritional supplements, hGH, hPG, blood products, heart valves, and
the many more products that come from bovine, ovine, or porcine tissues and
organs. So, as I said, this CWD would be a small piece of a very big puzzle.
But, it is here, and it most likely has killed. You see, greed is what caused
this catastrophe, rendering and feeding practices. But, once Pandora's box was
opened, the potential routes of infection became endless.
No BSE in the U.S.A.? I would not be so sure of that considering that since
1990;
Since 1990 the U.S. has raised 1,250,880,700 cattle;
Since 1990 the U.S. has ONLY checked 8,881 cattle brains for BSE, as of
Oct. 4, 1999;
There are apprx. 100,000 DOWNER cattle annually in the U.S., that up until
Aug. 4, 1997 went to the renders for feed;
Scrapie running rampant for years in the U.S., 950 infected FLOCKS, as of
Aug. 1999;
Our feeding and rendering practices have mirrored that of the U.K. for
years, some say it was worse. Everything from the downer cattle, to those
scrapie infected sheep, to any roadkill, including the city police horse and the
circus elephant went to the renders for feed and other products for consumption.
Then they only implemented a partial feed ban on Aug. 4, 1997, but pigs,
chickens, dogs, and cats, and humans were exempt from that ban. So they can
still feed pigs and chickens those potentially TSE tainted by-products, and then
they can still feed those by-products back to the cows. I believe it was Dr. Joe
Gibbs, that said, the prion protein, can survive the digestinal track. So you
have stopped nothing. It was proven in Oprah Winfrey's trial, that Cactus Cattle
feeders, sent neurologically ill cattle, some with encephalopathy stamped on the
dead slips, were picked up and sent to the renders, along with sheep carcasses.
Speaking of autopsies, I have a stack of them, from CJD victims. You would be
surprised of the number of them, who ate cow brains, elk brains, deer brains, or
hog brains.
I believe all these TSE's are going to be related, and originally caused by
the same greedy Industries, and they will be many. Not just the Renders, but you
now see, that they are re-using medical devices that were meant for disposal.
Some medical institutions do not follow proper auto- claving procedures (even
Olympus has put out a medical warning on their endescopes about CJD, and the
fact you cannot properly clean these instruments from TSE's), and this is just
one product. Another route of infection.
Regardless what the Federal Government in the U.S. says. It's here, I have
seen it, and the longer they keep sweeping it under the rug and denying the fact
that we have a serious problem, one that could surpass aids (not now, but in the
years to come, due to the incubation period), they will be responsible for the
continued spreading of this deadly disease.
It's their move, it's CHECK, but once CHECKMATE has been called, how many
thousands or millions, will be at risk or infected or even dead. You can't play
around with these TSE's. I cannot stress that enough. They are only looking at
body bags, and the fact the count is so low. But, then you have to look at the
fact it is not a reportable disease in most states, mis-diagnosis, no autopsies
performed. The fact that their one-in-a- million theory is a crude survey done
about 5 years ago, that's a joke, under the above circumstances. A bad joke
indeed........
The truth will come, but how many more have to die such a hideous death.
It's the Government's call, and they need to make a serious move, soon. This
problem, potential epidemic, is not going away, by itself.

U.S. Scientist should be concerned with a CJD epidemic in the U.S., as
well...
2 January 2000
Terry S Singeltary
In reading your short article about 'Scientist warn of CJD epidemic' news
in brief Jan. 1, 2000. I find the findings in the PNAS old news, made famous
again. Why is the U.S. still sitting on their butts, ignoring the facts? We have
the beginning of a CJD epidemic in the U.S., and the U.S. Gov. is doing
everything in it's power to conceal it.
The exact same recipe for B.S.E. existed in the U.S. for years and years.
In reading over the Qualitative Analysis of BSE Risk Factors-1, this is a 25
page report by the USDA:APHIS:VS. It could have been done in one page. The first
page, fourth paragraph says it all;
"Similarities exist in the two countries usage of continuous rendering
technology and the lack of usage of solvents, however, large differences still
remain with other risk factors which greatly reduce the potential risk at the
national level."
Then, the next 24 pages tries to down-play the high risks of B.S.E. in the
U.S., with nothing more than the cattle to sheep ratio count, and the
geographical locations of herds and flocks. That's all the evidence they can
come up with, in the next 24 pages.
Something else I find odd, page 16;
"In the United Kingdom there is much concern for a specific continuous
rendering technology which uses lower temperatures and accounts for 25 percent
of total output. This technology was _originally_ designed and imported from the
United States. However, the specific application in the production process is
_believed_ to be different in the two countries."
A few more factors to consider, page 15;
"Figure 26 compares animal protein production for the two countries. The
calculations are based on slaughter numbers, fallen stock estimates, and product
yield coefficients. This approach is used due to variation of up to 80 percent
from different reported sources. At 3.6 million tons, the United States produces
8 times more animal rendered product than the United Kingdom."
"The risk of introducing the BSE agent through sheep meat and bone meal is
more acute in both relative and absolute terms in the United Kingdom (Figures 27
and 28). Note that sheep meat and bone meal accounts for 14 percent, or 61
thousand tons, in the United Kingdom versus 0.6 percent or 22 thousand tons in
the United States. For sheep greater than 1 year, this is less than one-tenth of
one percent of the United States supply."
"The potential risk of amplification of the BSE agent through cattle meat
and bone meal is much greater in the United States where it accounts for 59
percent of total product or almost 5 times more than the total amount of
rendered product in the United Kingdom."
Considering, it would only take _one_ scrapie infected sheep to contaminate
the feed. Considering Scrapie has run rampant in the U.S. for years, as of Aug.
1999, 950 scrapie infected flocks. Also, Considering only one quarter spoonful
of scrapie infected material is lethal to a cow.
Considering all this, the sheep to cow ration is meaningless. As I said,
it's 24 pages of B.S.e.

"Löcher wie in einem Schweizer Käse" hat auch Terry Singeltary im Regelwerk
der FDA ausgemacht. Der Texaner kam auf einem tragischen Umweg zu dem Thema:
Nachdem seine Mutter 1997 binnen weniger Wochen an der
Creutzfeldt-Jakob-Krankheit gestorben war, versuchte er, die Ursachen der
Infektion aufzuspüren. Er klagte auf die Herausgabe von Regierungsdokumenten und
arbeitete sich durch Fachliteratur; heute ist er überzeugt, dass seine Mutter
durch die stetige Einnahme von angeblich kräftigenden Mitteln erkrankte, in
denen - völlig legal - Anteile aus Rinderprodukten enthalten sind.
Von der Fachwelt wurde Singeltary lange als versponnener Außenseiter
belächelt. Doch mittlerweile sorgen sich auch Experten, dass ausgerechnet diese
verschreibungsfreien Wundercocktails zur Stärkung von Intelligenz, Immunsystem
oder Libido von den Importbeschränkungen ausgenommen sind. Dabei enthalten die
Pillen und Ampullen, die in Supermärkten verkauft werden, exotische Mixturen aus
Rinderaugen; dazu Extrakte von Hypophyse oder Kälberföten, Prostata, Lymphknoten
und gefriergetrocknetem Schweinemagen. In die USA hereingelassen werden auch
Blut, Fett, Gelatine und Samen. Diese Stoffe tauchen noch immer in US-Produkten
auf, inklusive Medizin und Kosmetika. Selbst in Impfstoffen waren möglicherweise
gefährliche Rinderprodukte enthalten. Zwar fordert die FDA schon seit acht
Jahren die US-Pharmaindustrie auf, keine Stoffe aus Ländern zu benutzen, in
denen die Gefahr einer BSE-Infizierung besteht. Aber erst kürzlich
verpflichteten sich fünf Unternehmen, darunter Branchenführer wie
GlaxoSmithKline, Aventis und American Home Products, ihre Seren nur noch aus
unverdächtigem Material herzustellen.

BSE TSE PRION USDA FDA MAD COW FEED COMPLIANCE REPORT and NAI, OAI, and VAI
ratings as at June 5, 2013
Greetings,
since our fine federal friends have decided not to give out any more
reports on the USA breaches of the feed ban and surveillance etc. for the BSE
TSE prion mad cow type disease in the USDA livestock, I thought I might attempt
it. I swear, I just don’t understand the logic of the SSS policy, and that
includes all of it. I assure you, it would be much easier, and probably better
for the FDA and the USDA INC., if they would simply put some kind of report out
for Pete’s sake, instead of me doing it after I get mad, because I am going to
put it all out there. the truth.
PLEASE BE ADVISED, any breach of any of the above classifications OAI, VAI,
RTS, CAN lead to breaches into the feed BSE TSE prion protocols, and CAN lead to
the eventual suspect tainted feed reaching livestock. please, if any USDA
official out there disputes this, please explain then how they could not.
paperwork errors can eventually lead to breaches of the BSE TSE prion mad cow
feed ban reaching livestock, or contamination and exposure there from, as well.
I would sure like to see the full reports of just these ;

a short brief update on the mad cow bse follies, and our good friend Lester
Crawford that was at the FDA.
ALSO, I would kindly like to comment on this FDA BSE/Ruminant Feed
Inspections Firms Inventory (excel format)4 format, for reporting these breaches
of BSE TSE prion protocols, from the extensive mad cow feed ban warning letters
the fda use to put out for each violations. simply put, this excel format sucks,
and the FDA et al intentionally made it this difficult to follow the usda fda
mad cow follies. this is an intentional format to make it as difficult as
possible to follow these breaches of the mad cow TSE prion safety feed
protocols. to have absolutely no chronological or numerical order, and to format
such violations in a way that they are almost impossible to find, says a lot
about just how far the FDA and our fine federal friends will go through to hide
these continued violations of the BSE TSE prion mad cow feed ban, and any
breaches of protocols there from. once again, the wolf guarding the henhouse $$$
NAI = NO ACTION INDICATED
OAI = OFFICIAL ACTION INDICATED
VAI = VOLUNTARY ACTION INDICATED
RTS = REFERRED TO STATE
Inspections conducted by State and FDA investigators are classified to
reflect the compliance status at the time of the inspection, based upon whether
objectionable conditions were documented. Based on the conditions found,
inspection results are recorded in one of three classifications:
OAI (Official Action Indicated) when inspectors find significant
objectionable conditions or practices and believe that regulatory sanctions are
warranted to address the establishment’s lack of compliance with the regulation.
An example of an OAI classification would be findings of manufacturing
procedures insufficient to ensure that ruminant feed is not contaminated with
prohibited material. Inspectors will promptly re-inspect facilities classified
OAI after regulatory sanctions have been applied to determine whether the
corrective actions are adequate to address the objectionable conditions.
VAI (Voluntary Action Indicated) when inspectors find objectionable
conditions or practices that do not meet the threshold of regulatory
significance, but warrant an advisory to inform the establishment that
inspectors found conditions or practices that should be voluntarily corrected.
VAI violations are typically technical violations of the 1997 BSE Feed Rule.
These violations include minor recordkeeping lapses or conditions involving
non-ruminant feeds.
NAI (No Action Indicated) when inspectors find no objectionable conditions
or practices or, if they find objectionable conditions, those conditions are of
a minor nature and do not justify further actions.
when sound science was bought off by junk science, in regards to the BSE
TSE prion mad cow type disease, by the USDA, CFIA, WHO, OIE, et al. $$$
when the infamous, and fraudulently USDA, FSIS, APHIS, FDA, gold card was
taken away that infamous day in December of 2003, all cards were off the table,
it was time to change the science, and change they did. ...tss

Suspect symptoms
What if you can catch old-fashioned CJD by eating meat from a sheep
infected with scrapie?
28 Mar 01
Like lambs to the slaughter 31 March 2001 by Debora MacKenzie Magazine
issue 2284. Subscribe and get 4 free issues. FOUR years ago, Terry Singeltary
watched his mother die horribly from a degenerative brain disease. Doctors told
him it was Alzheimer's, but Singeltary was suspicious. The diagnosis didn't fit
her violent symptoms, and he demanded an autopsy. It showed she had died of
sporadic Creutzfeldt-Jakob disease.
Most doctors believe that sCJD is caused by a prion protein deforming by
chance into a killer. But Singeltary thinks otherwise. He is one of a number of
campaigners who say that some sCJD, like the variant CJD related to BSE, is
caused by eating meat from infected animals. Their suspicions have focused on
sheep carrying scrapie, a BSE-like disease that is widespread in flocks across
Europe and North America.
Now scientists in France have stumbled across new evidence that adds weight
to the campaigners' fears. To their complete surprise, the researchers found
that one strain of scrapie causes the same brain damage in mice as sCJD.
"This means we cannot rule out that at least some sCJD may be caused by
some strains of scrapie," says team member Jean-Philippe Deslys of the French
Atomic Energy Commission's medical research laboratory in Fontenay-aux-Roses,
south-west of Paris. Hans Kretschmar of the University of Göttingen, who
coordinates CJD surveillance in Germany, is so concerned by the findings that he
now wants to trawl back through past sCJD cases to see if any might have been
caused by eating infected mutton or lamb.
Scrapie has been around for centuries and until now there has been no
evidence that it poses a risk to human health. But if the French finding means
that scrapie can cause sCJD in people, countries around the world may have
overlooked a CJD crisis to rival that caused by BSE.
Deslys and colleagues were originally studying vCJD, not sCJD. They
injected the brains of macaque monkeys with brain from BSE cattle, and from
French and British vCJD patients. The brain damage and clinical symptoms in the
monkeys were the same for all three. Mice injected with the original sets of
brain tissue or with infected monkey brain also developed the same symptoms.
As a control experiment, the team also injected mice with brain tissue from
people and animals with other prion diseases: a French case of sCJD; a French
patient who caught sCJD from human-derived growth hormone; sheep with a French
strain of scrapie; and mice carrying a prion derived from an American scrapie
strain. As expected, they all affected the brain in a different way from BSE and
vCJD. But while the American strain of scrapie caused different damage from
sCJD, the French strain produced exactly the same pathology.
"The main evidence that scrapie does not affect humans has been
epidemiology," says Moira Bruce of the neuropathogenesis unit of the Institute
for Animal Health in Edinburgh, who was a member of the same team as Deslys.
"You see about the same incidence of the disease everywhere, whether or not
there are many sheep, and in countries such as New Zealand with no scrapie." In
the only previous comparisons of sCJD and scrapie in mice, Bruce found they were
dissimilar.
But there are more than 20 strains of scrapie, and six of sCJD. "You would
not necessarily see a relationship between the two with epidemiology if only
some strains affect only some people," says Deslys. Bruce is cautious about the
mouse results, but agrees they require further investigation. Other trials of
scrapie and sCJD in mice, she says, are in progress.
People can have three different genetic variations of the human prion
protein, and each type of protein can fold up two different ways. Kretschmar has
found that these six combinations correspond to six clinical types of sCJD: each
type of normal prion produces a particular pathology when it spontaneously
deforms to produce sCJD.
But if these proteins deform because of infection with a disease-causing
prion, the relationship between pathology and prion type should be different, as
it is in vCJD. "If we look at brain samples from sporadic CJD cases and find
some that do not fit the pattern," says Kretschmar, "that could mean they were
caused by infection."
There are 250 deaths per year from sCJD in the US, and a similar incidence
elsewhere. Singeltary and other US activists think that some of these people
died after eating contaminated meat or "nutritional" pills containing dried
animal brain. Governments will have a hard time facing activists like Singeltary
if it turns out that some sCJD isn't as spontaneous as doctors have insisted.
Deslys's work on macaques also provides further proof that the human
disease vCJD is caused by BSE. And the experiments showed that vCJD is much more
virulent to primates than BSE, even when injected into the bloodstream rather
than the brain. This, says Deslys, means that there is an even bigger risk than
we thought that vCJD can be passed from one patient to another through
contaminated blood transfusions and surgical instruments.

Atypical/Nor98 Scrapie Infectivity in Sheep Peripheral Tissues

5. A positive result from a chimpanzee challenged severly would likely
create alarm in some circles even if the result could not be interpreted for
man. I have a view that all these agents could be transmitted provided a large
enough dose by appropriate routes was given and the animals kept long enough.
Until the mechanisms of the species barrier are more clearly understood it might
be best to retain that hypothesis.

Experimental Oral Transmission of Atypical Scrapie to Sheep
Volume 17, Number 5-May 2011 However, work with transgenic mice has
demonstrated the potential susceptibility of pigs, with the disturbing finding
that the biochemical properties of the resulting PrPSc have changed on
transmission (40).
***The pathology features of Nor98 in the cerebellum of the affected sheep
showed similarities with those of sporadic Creutzfeldt-Jakob disease in humans.
*** Intriguingly, these conclusions suggest that some pathological features
of Nor98 are reminiscent of Gerstmann-Sträussler-Scheinker disease.
*** These observations support the view that a truly infectious TSE agent,
unrecognized until recently, infects sheep and goat flocks and may have
important implications in terms of scrapie control and public health.
Surprisingly the TSE agent characteristics were dramatically different
v/hen passaged into Tg bovine mice. The recovered TSE agent had biological and
biochemical characteristics similar to those of atypical BSE L in the same mouse
model. Moreover, whereas no other TSE agent than BSE were shown to transmit into
Tg porcine mice, atypical scrapie was able to develop into this model, albeit
with low attack rate on first passage.
Furthermore, after adaptation in the porcine mouse model this prion showed
similar biological and biochemical characteristics than BSE adapted to this
porcine mouse model. Altogether these data indicate.
(i) the unsuspected potential abilities of atypical scrapie to cross
species barriers
(ii) the possible capacity of this agent to acquire new characteristics
when crossing species barrier
These findings raise some interrogation on the concept of TSE strain and on
the origin of the diversity of the TSE agents and could have consequences on
field TSE control measures.

A kind greetings from Bacliff, Texas !
I have often pondered if the whole damn mad cow follies started over here
in the USA, and somehow, the USA shipped it over to the UK ?
It happened with S. Korea and CWD, via Canada. see ;
The disease was confirmed only in elk in the Republic of Korea in 2001,
2004 and 2005. Epidemiological investigations showed that CWD was introduced via
importation of infected elk from Canada between 1994 and 1997.
but I still am not so sure that the mad cow follies did not start long ago
right here in the USA i.e. Richard Marsh and deadstock downer cattle to those
mink, and then the USA shipped it to hell and back. just pondering out loud
here. ...tss
