CJD Mark Tami: To ask the Secretary of State for Health (1) what steps his
Department has put in place to monitor the number of people who carry the
abnormal prion protein which causes variant Creutzfeldt-Jakob disease;
[174628]
(2) when he plans that screening of the abnormal prion protein which causes
variant Creutzfeldt-Jakob disease will be introduced; [174631]
(3) what assessment he has made of the number of people who carry the
abnormal prion protein which causes variant Creutzfeldt-Jakob disease.
[174633]
12 Nov 2013 : Column 615W
Jane Ellison: The presence of abnormal prion protein is currently taken as
a marker for asymptomatic carriage of variant Creutzfeldt-Jakob disease or for
symptomatic infection. A recent study to assess carriage by looking at stored
appendix tissue samples, first published in the Health Protection Report in
August 2012, found abnormal prion protein in 16 appendices out of 32,441
samples. This suggests a prevalence of about 1 in 2,000.
There is no monitoring of people who may carry the abnormal prion protein;
all appendix prevalence studies are anonymised.
No routine screening can yet take place as there are no suitable validated
screening tests for abnormal prion protein available. The Department, together
with the United Kingdom Blood Services, continues to monitor, scientific
research and development in this area.

I AGREE WITH MR. BULLARD, it’s all about trade and money, BSE TSE PRION aka
mad cow type disease and sound science there from, was thrown out the window by
the USDA et al that fateful day in December 23, 2003, when the USDA lost it’s
‘gold card’ of supposedly being BSE FREE, (that was and still is a sad joke
though), that’s when mad cow junk science was adopted by the USDA...

AD.56: The emergence of novel BSE prions by serial passages of H-type BSE
in bovinized mice

H-type bovine spongiform encephalopathy (BSE) is an atypical form of BSE,
and has been detected in several European countries, and North America.
Transmission studies of H-type BSE led to the emergence of the classical BSE
(C-BSE) phenotypes during passages in inbred wild type and bovinized
PrP-overexpressing transgenic mice. In this study, we conducted serial passages
of Canadian H-type BSE isolate in bovinized PrP-overexpressing transgenic mice
(TgBoPrP). H-type BSE isolate was transmitted to TgBoPrP with incubation periods
of 320 ± 12.2 d at primary passage. The incubation period of 2nd and 3rd passage
were constant (~= 220 d), no clear differences were observed in their biological
and biochemical properties. However, at the forth passage, 2 different BSE
phenotypes were confirmed; one is shorter survival times (109 ± 4 d) and the
other is longer survival times. TgBoPrP mice with longer incubation period
showed the H-type phenotype of PrPsc profile and pathology. However, those of
shorter incubation period were different phenotypes from previously existed BSE
prions (C-BSE, L-type BSE, and H-type BSE).

virulence in cattle will be emerged during intraspecies transmission.

*** Evaluation of the Zoonotic Potential of Transmissible Mink
Encephalopathy
We previously described the biochemical similarities between PrPres derived
from L-BSE infected macaque and cortical MM2 sporadic CJD: those observations
suggest a link between these two uncommon prion phenotypes in a primate model
(it is to note that such a link has not been observed in other models less
relevant from the human situation as hamsters or transgenic mice overexpressing
ovine PrP [28]). We speculate that a group of related animal prion strains
(L-BSE, c-BSE and TME) would have a zoonotic potential and lead to prion
diseases in humans with a type 2 PrPres molecular signature (and more
specifically type 2B for vCJD)
snip...
Together with previous experiments performed in ovinized and bovinized
transgenic mice and hamsters [8,9] indicating similarities between TME and
L-BSE, the data support the hypothesis that L-BSE could be the origin of the TME
outbreaks in North America and Europe during the mid-1900s.

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
