''DH is aware of a second case of CJD in a dairy farmer who has had BSE in his herd. We cannot comment on the details of the case, but we know of nothing to suggest this is anthing other than a sporadic case of CJD. .........
THE FARMER IS THOUGHT TO HAVE HAD AT LEAST TWO CASES OF BSE IN HIS HERD, which were diagnosed in 1992. The farmer is reported to have asssisted in calving and to have drunk milk from his herd. This does not suggest that this is anything other than a sporadic case of CJD. ...

Ministers will note from this that experts are of the view, that there is unlikely to be a direct link between the cases of BSE, and the occurance of CJD in the farmer.
'AGE AT ONSET' is therefore likely to be a reflection of particulary aetiological factors, about which, for sporadic CJD at least, much is yet unknown. IT has therefore been suggested that examination of the f/d i/p of other groups with TSE's, and comparison with that of CJD subsets might help to elucidate aetiological mechanisms for sporadic CJD in particular; i.e. ALMOST A REVERSAL OF THE ORIGINAL UNDERTAKING.

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.

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.

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

(take these old snips of emails with how ever many grains of salt you wish. ...tss)
The most frightening thing I have read all day is the report of Gambetti's finding of a new strain of sporadic cjd in young people...Dear God, what in the name of all that is holy is that!!! If the US has different strains of scrapie.....why????than the UK...then would the same mechanisms that make different strains of scrapie here make different strains of BSE...if the patterns are different in sheep and mice for scrapie.....could not the BSE be different in the cattle, in the mink, in the humans.......I really think the slides or tissues and everything from these young people with the new strain of sporadic cjd should be put up to be analyzed by many, many experts in cjd........bse.....scrapie Scrape the damn slide and put it into mice.....wait.....chop up the mouse brain and and spinal cord........put into some more mice.....dammit amplify the thing and start the damned research.....This is NOT rocket science...we need to use what we know and get off our butts and move....the whining about how long everything takes.....well it takes a whole lot longer if you whine for a year and then start the research!!! Not sure where I read this but it was a recent press release or something like that: I thought I would fall out of my chair when I read about how there was no worry about infectivity from a histopath slide or tissues because they are preserved in formic acid, or formalin or formaldehyde.....for God's sake........ Ask any pathologist in the UK what the brain tissues in the formalin looks like after a year.......it is a big fat sponge...the agent continues to eat the brain ......you can't make slides anymore because the agent has never stopped........and the old slides that are stained with Hemolysin and Eosin......they get holier and holier and degenerate and continue...what you looked at 6 months ago is not there........Gambetti better be photographing every damned thing he is looking at.....
Okay, you need to know. You don't need to pass it on as nothing will come of it and there is not a damned thing anyone can do about it. Don't even hint at it as it will be denied and laughed at.......... USDA is gonna do as little as possible until there is actually a human case in the USA of the nvcjd........if you want to move this thing along and shake the earth....then we gotta get the victims families to make sure whoever is doing the autopsy is credible, trustworthy, and a saint with the courage of Joan of Arc........I am not kidding!!!! so, unless we get a human death from EXACTLY the same form with EXACTLY the same histopath lesions as seen in the UK nvcjd........forget any action........it is ALL gonna be sporadic!!!
And, if there is a case.......there is gonna be every effort to link it to international travel, international food, etc. etc. etc. etc. etc. They will go so far as to find out if a sex partner had ever traveled to the UK/europe, etc. etc. .... It is gonna be a long, lonely, dangerous twisted journey to the truth. They have all the cards, all the money, and are willing to threaten and carry out those threats....and this may be their biggest downfall...
Thanks as always for your help. (Recently had a very startling revelation from a rather senior person in government here..........knocked me out of my chair........you must keep pushing. If I was a power person....I would be demanding that there be a least a million bovine tested as soon as possible and agressively seeking this disease. The big players are coming out of the woodwork as there is money to be made!!! In short: "FIRE AT WILL"!!! for the very dumb....who's "will"! "Will be the burden to bare if there is any coverup!"
again it was said years ago and it should be taken seriously....BSE will NEVER be found in the US! As for the BSE conference call...I think you did a great service to freedom of information and making some people feign integrity...I find it scary to see that most of the "experts" are employed by the federal government or are supported on the "teat" of federal funds. A scary picture! I hope there is a confidential panel organized by the new government to really investigate this thing.
You need to watch your back........but keep picking at them.......like a buzzard to the bone...you just may get to the truth!!! (You probably have more support than you know. Too many people are afraid to show you or let anyone else know. I have heard a few things myself... you ask the questions that everyone else is too afraid to ask.)

Background, Concerns about the blood-borne risk of prion infection have been confirmed by the occurrence in the UK of four transfusion-related infections of vCJD and an apparently silent infection in an hemophiliac patient. Asymptomatic incubation periods in prion diseases can extend over decades in humans. We present here unexpected results of experiments evaluating blood transmission risk in a non-human primate model.
Material and Methods, Cynomolgus macaques were inoculated with brain or blood specimens from vCJD infected humans or monkeys. Neuropathological and biochemical findings were obtained using current methods used for human patients.
Results, Thirteen out of 23 primates exposed to various human or macaque blood products exhibited a previously undescribed myelopathic syndrome, devoid of the classical features of prion disease, notably abnormal prion protein (PrPres) deposition, whereas the 14 corresponding brain-inoculated donor animals and 1 transfused animal exhibited the classical vCJD pattern. In passage experiments, plasma transfusion induced the same atypical phenotype after two years (again, with no detectable PrPres), whereas the intracerebral inoculation of spinal cord led to a typical prion disease with cerebral spongiosis and PrPres accumulation in the brain of the primate recipient. Interestingly, passage experiments in transgenic mice were largely unsuccessful.
In another experiment designed to test the efficacy of antiprion filters, three recipients of filtered red blood cells suspended in plasma are still healthy 4.5 y after transfusion whereas the recipients of unfiltered inocula died after 2.5 y with the atypical neurological profile.
Conclusion. We describe a new fatal neurological myelopathic syndrome in monkeys exposed to various vCJD/BSE-infected blood components.
Secondary transmission in primates confirms
(I) the transmissibility of this myelopathy, and
(2) its prion origin which could not be diagnosed as such in the first recipients.
This myelopathy might be compared in some respects to certain forms of human lower motor neuron disease, including neuromyelitis optica, the flail arm syndrome of amyotrophic lateral sclerosis (ALS), and the recently described FOSMN (facial onset sensory and motor neuronopathy) syndrome.

AD.56: The emergence of novel BSE prions by serial passages of H-type BSE in bovinized mice
Kentaro Masujin, Naoko Tabeta, Ritsuko Miwa, Kohtaro Miyazawa, Hiroyuki Okada, Shirou Mohri and Takashi Yokoyama
National Institute of Animal Health; Tsukuba, Japan
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).
*** This study imply the possibility that the novel BSE prions with high virulence in cattle will be emerged during intraspecies transmission.

In the Archives of Neurology you quoted (the abstract of which was attached to your email), we did not say CWD in humans will present like variant CJD.
That assumption would be wrong. I encourage you to read the whole article and call me if you have questions or need more clarification (phone: 404-639-3091). Also, we do not claim that "no-one has ever been infected with prion disease from eating venison."

Cross-sequence transmission of sporadic Creutzfeldt-Jakob disease creates a new prion strain
Date: August 25, 2007 at 12:42 pm PST
our results raise the possibility that CJD cases classified as VV1 may include cases caused by iatrogenic transmission of sCJD-MM1 prions or food-borne infection by type 1 prions from animals, e.g., chronic wasting disease prions in cervid. In fact, two CJD-VV1 patients who hunted deer or consumed venison have been reported (40, 41). The results of the present study emphasize the need for traceback studies and careful re-examination of the biochemical properties of sCJD-VV1 prions.

HD.13: CWD infection in the spleen of humanized transgenic mice
Liuting Qing and Qingzhong Kong
Case Western Reserve University; Cleveland, OH USA
Chronic wasting disease (CWD) is a widespread prion disease in free-ranging and captive cervid species in North America, and there is evidence suggesting the existence of multiple CWD strains. The susceptibility of human CNS and peripheral organs to the various CWD prion strains remains largely unclear. Current literature suggests that the classical CWD strain is unlikely to infect human brain, but the potential for peripheral infection by CWD in humans is unknown. We detected protease-resistant PrpSc in the spleens of a few humanized transgenic mice that were intracerebrally inoculated with natural CWD isolates, but PrpSc was not detected in the brains of any of the CWD-inoculated mice. Our ongoing bioassays in humanized Tg mice indicate that intracerebral challenge with such PrpSc-positive humanized mouse spleen already led to prion disease in most animals. ***These results indicate that the CWD prion may have the potential to infect human peripheral lymphoid tissues.

Background. Bovine spongiform encephalopathy (BSE) is a known zoonotic prion disease, resulting in variant Creurzfeldt- Jakob disease (vCJD) in humans. In contrast, classical scrapie in sheep is thought to offer little or no danger to human health. However, a widening range of prion diseases have been recognized in cattle, sheep and deer. The risks posed by individual animal prion diseases to human health cannot be determined a priori and are difficult to assess empirically. The fundamemal event in prion disease pathogenesis is thought to be the seeded conversion of normal prion protein (PrPC) to its pathological isoform (PrPSc). Here we report the use of a rapid molecular conversion assay to test whether brain specimens from different animal prion diseases are capable of seeding the conversion of human PrPC ro PrPSc.
Material and Methods. Classical BSE (C-type BSE), H-type BSE, L-type BSE, classical scrapie, atypical scrapie, chronic wasting disease and vCJD brain homogenates were tested for their ability to seed conversion of human PrPC to PrPSc in protein misfolding cyclic amplification (PMCA) reactions. Newly formed human PrPSc was detected by protease digestion and western blotting using the antibody 3F4.
Results. C-type BSE and vCJD were found to efficiently convert PrPC to PrPSc. Scrapie failed to convert human PrPC to PrPSc. Of the other animal prion diseases tested only chronic wasting disease appeared to have the capability ro convert human PrPC to PrPSc. The results were consistent whether the human PrPC came from human brain, humanised transgenic mouse brain or from cultured human cells and the effect was more pronounced for PrPC with methionine at codon 129 compared with that with valine.
Conclusion. Our results show that none of the tested animal prion disease isolates are as efficient as C-type BSE and vCJD in converting human prion protein in this in vitro assay. ***However, they also show that there is no absolute barrier ro conversion of human prion protein in the case of chronic wasting disease.

Invited.16: Studies of chronic wasting disease transmission in cervid and non-cervid species

How and why some misfolded proteins become horizontally transmitted agents and occasionally cross species barriers are issues fundamental to understanding prion disease. Chronic wasting disease (CWD) of cervids is perhaps a prototype of horizontal prion transmission, encompassing efficient mucosal uptake, lymphoid amplification, neuroinvasion, peripheralization, and dissemination via mucosal excretion. Efficient mucosal transmission of CWD in deer has been demonstrated by oral, nasal, aerosol, and indirect contact exposure. In addition, other studies (Mathiason CK, et al.) reported at the symposium support a significant role for pre- and/or postnatal transmission of CWD from doe to offspring. Accumulating, yet still incomplete, evidence also suggests that the period of relatively covert CWD infection may be longer than originally thought. Given the above, minimally invasive sensitive assays based on body fluids from live animals would aid substantially in understanding the biology of CWD. We have been applying seeded realtirne quaking-induced amplification of recombinant PrP substrates (i.e., RT-QuIC methodology) to: (1) investigate antemortem CWD detection, and (2) model PrP-based species barriers and trans-species adaptation-topics we previously explored using sPMCA and in vivo bioassays. At this symposium, we report sensitive and specific detection CWD prions in saliva, urine, blood (Mathiason lab), and rectal and pharyngeal lymph node samples (Haley NJ, et al.) from pre-symptomatic and symptomatic experimentally and naturally exposed deer. Other ongoing studies are employing RT-QuIC methodology to model amplification barriers among CWD, FSE, BSE, and CJD prions using cervine, feline, bovine, human, and promiscuous rPrP substrates and the above species prion seeds, cellular co-factors, and transgenic mice. Finally, in collaboration with the Wisniewski laboratory, we are conducting of experimental CWD vaccination studies in deer employing oral administration of an attenuated Salmonella vector expressing cervid PrP epitopes.

AD.06: Detecting prions in the brain and blood of TSE-infected deer and hamsters

While large quantities of protease resistant prion protein (PrPres) can be demonstrated by western blot or IHC in lymphoid biopsies or post-mortem brain tissues harvested from prion-infected animals, these conventional assays are less reliable as means to detect the small quantities of prions thought to be present in bodily fluids or associated with early and asymptomatic phases of TSE disease. The Real Time-Quaking Induced Conversion (RT-QuIC) assay is capable of detecting prions at concentrations below the level of sensitivity of conventional assays and provides a real-time fluorescent readout negating the use of proteases. We have made modifications to the RT-QuIC assay to utilize it for the detection of PrPres in brain and blood harvested from various species infected with prions. In this study, we analyzed CWD-infected deer and CWD/TME-infected hamster whole blood to determine the effect of:
(1) various anticoagulants,
(2) freezing and
(3) NaPTA precipitation.
Brain tissue and blood collected from naive deer and hamsters served as negative controls.
We were able to demonstrate amplifiable prions in
(1) brain and blood samples harvested from CWD/TME-infected animals,
(2) heparinized blood,
(3) frozen vs. fresh blood and
(4) NaPTA treated samples.
The RT-QuIC assay is able to detect PrPres in various species of animals and shows promise as an antemortem diagnostic tool for blood-borne TSEs.

*** As Chronic Wasting Disease CWD rises in deer herd, what about risk for humans?
http://chronic-wasting-disease.blogspot.com/2013/07/as-chronic-wasting-disease-cwd-rises-in.html
sCJDMM1-2 should be considered as a separate entity at this time.

*** 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.
