First probable human case of mad cow disease in Taiwan was listed posthumously 2010/12/18 21:14:28
1st case of probable mad cow disease listed posthumously in Taiwan 2010/12/18 21:14:28
Taipei, Dec. 18 (CNA) The first probable human case of mad cow disease in Taiwan was listed posthumously Saturday, following the death in May of a man who had symptoms of the fatal brain-wasting illness.
The listing was made after officials and experts on a Department of Health (DOH) panel on Creutzfeldt-Jakob Disease (CJD) held a meeting to determine whether the man had died from the disease as result of eating infected beef.
"We believe it is very likely that the man who died in May this year contracted the disease during his stay in the United Kingdom, " the DOH said in a press statement. "We cannot rule out the possibility that he ate infected beef during that time."
Scientists believe that many years after eating cattle infected with bovine spongiform encephalopathy (BSE) , commonly known as mad cow disease, humans can develop symptoms of new variant CJD (vCJD) , also known as human mad cow disease.
The 36-year-old man had lived in the U.K. between 1989 and 1997, when mad cow disease was at its peak in that country. He began to show vCJD symptoms, including memory loss and hypersomnia, in 2008. Doctors reported the case to the DOH's Centers for Disease Control in March 2009.
As his family refused to give doctors permission to perform an autopsy, the DOH said, it could not list the patient as a confirmed case of vCJD. His body has since been cremated.
Though the cause of death could not be determined by means of an autopsy, it was an extremely likely case of vCJD, based on the man's symptoms, travel history and the results of magnetic resonance imaging and electroencephalograms, the DOH said.
According to the DOH's CJD advisory panel, it was unlikely that the patient contracted the disease in Taiwan.
"His death could be counted as an imported case of vCJD and unlikely to pose any threat to Taiwan's disease control network," the DOH statement said.
Citing its tracking records, the DOH said the man had donated blood to two patients 10 years ago.
"Neither of them has contracted the disease," the statement said, adding that precautionary measures had been taken to prevent any spread of the disease during the time the man was hospitalized in Taiwan.
According to the World Health Organization, CJD is a fatal human degenerative condition characterized by progressive brain dysfunction and is categorized into four forms -- sporadic, familial, iatrogenic and variant.
The UK Department of Health has said vCJD differs from CJD in that the former is more likely to strike younger people.
Since 1997 when the DOH set up a CJD reporting and monitoring system, 436 suspected CJD or vCJD have been reported in Taiwan, DOH figures show. Of that number, 246 were listed as possible or extremely possible cases of sporadic or familial forms of CJD, five were confirmed as traditional forms of CJD and one was listed as probable vCJD, according to the DOH tallies.
The others were ruled out as possible cases of CJD.

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

RRA&T 2 Senate Friday, 5 February 2010
RURAL AND REGIONAL AFFAIRS AND TRANSPORT
[9.03 am]
BELLINGER, Mr Brad, Chairman, Australian Beef Association
CARTER, Mr John Edward, Director, Australian Beef Association
CHAIR—Welcome. Would you like to make an opening statement?
Mr Bellinger—Thank you. The ABA stands by its submission, which we made on 14 December last year, that the decision made by the government to allow the importation of beef from BSE affected countries is politically based, not science based. During this hearing we will bring forward compelling new evidence to back up this statement. When I returned to my property after the December hearing I received a note from an American citizen. I will read a small excerpt from the mail he sent me in order to reinforce the dangers of allowing the importation of beef from BSE affected countries. I have done a number of press releases on this topic, and this fellow has obviously picked my details up from the internet. His name is Terry Singeltary and he is from Bacliff, Texas. He states, and rightfully so:
You should be worried. Please let me explain. I’ve kept up with the mad cow saga for 12 years today, on December 14th 1997, some four months post voluntary and partial mad cow feed ban in the USA, I lost my mother to the Heidenhain variant Creutzfeldt-Jakob disease (CJD). I know this is just another phenotype of the infamous sporadic CJDs. Here in the USA, when USA sheep scrapie was transmitted to USA bovine, the agent was not UK BSE—it was a different strain. So why then would human TSE from USA cattle look like UK CJD from UK BSE? It would not. So this accentuates that the science is inconclusive still on this devastating disease. He goes on to state:
The OIE— the International Organisation of Epizootics, the arm of the WTO— is a failed global agent that in my opinion is bought off via bogus regulations for global trade and industry reps. I have done this all these years for nothing but the truth. I am a consumer, I eat meat, but I do not have to sit idly by and see the ignorance and greed of it all while countless numbers of humans and animals are being exposed to the TSE agents. All the USA is interested in is trade, nothing else matters.
Even Dr Stanley Prusiner, who incidentally won the Nobel Health Prize in 1997 for his work on the prion—he invented the word ‘prion’, or it came from him—states:
The BSC policy was set up for one purpose only, trade—the illegal trading of all strains of TSE globally throughout North America, which is home to CBSC, IBSC and HBSC, many scrapie strains and two strains of CJD to date. (please note typo error, those should have read cBSE, lBSE, and hBSE...tss)
I would also like, while I have the opportunity, to explain the beef-off-the-shelves myth. At the first Senate hearing on 14 December, it was explained that the reason why they allowed BSC beef into Australia was the beef-off-the-shelves policy, whereby if we found a case of BSC in Australia they would have to recall all—

RURAL AND REGIONAL AFFAIRS AND TRANSPORT
Senator HEFFERNAN—Which of course is total BS.
Mr Bellinger—Correct. This is written in the FSANZ document—Food Standards Australia New Zealand. Why isn’t this same policy in New Zealand? It is not—it is only in Australia. We are the only country in the world to have this idiotic policy. So we again call for the tabling of the WTO obligations paperwork. We do not believe that exists.

Name: Terry S. Singeltary Sr. Date: Jan 26, 2007
Dear Terry S. Singeltary Sr.
My name in Seoungwon Lee and I work for National Assemblywoman (MP) Sang-Jeong Sim, in South Korea. Below is a message from Mr. Kwon. Please get back to us regarding the letter.
Thank you.
Seoungwon Lee Legislative Assistant National Assembly Republic of Korea
Dear Terry S. Singeltary Sr.
Greetings from Korea.
I have learned about what you and your family have been through a internet. Being the father of a small family, I can only imagine the sense of loss that you and your family still must feel regarding your mother.
Through the internet, many people here in Korea have learnt about the story of your family and it has created a great deal of concern. Your experience had particular relevance for the citizens here, for the Korean government, in connection to the free trade agreement it is negotiating with the United States, is about to restart the sale of the unsafe American beef to the general public.
The Korean government has already imported the first load American beef and is currently going through the inspection period. There has been a great deal of controversy regarding the safety of these products, and a precipitous increase in public interest regarding the causes and symptoms of vCJD.
It is in this context that we are preparing a session together with National Assembly members and relevant NGOs to hear from those who have had direct experience with the human variant of BSE. We are very interested in hearing about the symptoms that your mother showed, your views on the response from the US government to the many deaths that resulted from this disease, the reaction from the general public, and any other area that you would wish to speak about. There would also be experts and academics in the area to speak at the session as well. We believe that it would greatly contribute to raising awareness about the issue, as well as help politicians and civic activists to consider the repercussions of the beef import issue.
We would like to request your help in this regard. We are planning for the session to be held in Seoul on the 23rd of this November. We would very much like to have you present in order to help prevent such tragic incidents from happening in Korea. We would, of course, pay for the trip and accommodations for the duration of your stay. If you were to participate, we could also meet with members from the agricultural committee of the National Assembly and from other related organizations to urge more interest to the issue.
Please do not hesitate to offer suggestions or ask us any questions that you might have. We look forward to a positive response and to meeting you in Seoul.
Thank you.
Sincerely, Sim Sang-Jeong
Head of the Democratic Labor Party Parliamentary Committee on the Korea-US FTA Member of the National Assembly Republic of Korea

Comment 2006-2007 USA AND OIE POISONING GLOBE WITH BSE MRR POLICY
THE USA is in a most unique situation, one of unknown circumstances with human and animal TSE. THE USA has the most documented TSE in different species to date, with substrains growing in those species (BSE/BASE in cattle and CWD in deer and elk, there is evidence here with different strains), and we know that sheep scrapie has over 20 strains of the typical scrapie with atypical scrapie documented and also BSE is very likely to have passed to sheep. all of which have been rendered and fed back to animals for human and animal consumption, a frightening scenario. WE do not know the outcome, and to play with human life around the globe with the very likely TSE tainted products from the USA, in my opinion is like playing Russian roulette, of long duration, with potential long and enduring consequences, of which once done, cannot be undone. These are the facts as I have come to know through daily and extensive research of TSE over 9 years, since 12/14/97. I do not pretend to have all the answers, but i do know to continue to believe in the ukbsenvcjd only theory of transmission to humans of only this one strain from only this one TSE from only this one part of the globe, will only lead to further failures, and needless exposure to humans from all strains of TSE, and possibly many more needless deaths from TSE via a multitude of proven routes and sources via many studies with primates and rodents and other species.
MY personal belief, since you ask, is that not only the Canadian border, but the USA border, and the Mexican border should be sealed up tighter than a drum for exporting there TSE tainted products, until a validated, 100% sensitive test is available, and all animals for human and animal consumption are tested. all we are doing is the exact same thing the UK did with there mad cow poisoning when they exported it all over the globe, all the while knowing what they were doing. this BSE MRR policy is nothing more than a legal tool to do just exactly what the UK did...

Pertenece a: UCL University College London Eprints
Descripción: Transmission of prions between mammalian species is thought to be limited by a "species barrier," which depends on differences in the primary structure of prion proteins in the infecting inoculum and the host, Here we demonstrate that a strain of hamster prions thought to be nonpathogenic for conventional mice leads to prion replication to high levels in such mice but without causing clinical disease. Prions pathogenic in both mice and hamsters are produced. These results demonstrate the existence of subclinical forms of prion infection with important public health implications, both with respect to iatrogenic transmission from apparently healthy humans and dietary exposure to cattle and other species exposed to bovine spongiform encephalopathy prions, Current definitions of the species barrier, which have been based on clinical endpoints, need to be fundamentally reassessed.

Increased susceptibility of human-PrP transgenic mice to bovine spongiform encephalopathy following passage in sheep
http://bse-atypical.blogspot.com/2010/11/increased-susceptibility-of-human-prp.html
Seven main threats for the future linked to prions
The NeuroPrion network has identified 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.

Dear Sir/Madam, 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." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.

There are now two documented strains of CWD, and science is showing that indeed CWD could transmit to humans via transmission studies ;

Key words: CWD, strain, human transmission
Chronic wasting disease (CWD) is a widespread prion disease in cervids (deer and elk) in North America where significant human exposure to CWD is likely and zoonotic transmission of CWD is a concern. Current evidence indicates a strong barrier for transmission of the classical CWD strain to humans with the PrP-129MM genotype. A few recent reports suggest the presence of two or more CWD strains. What remain unknown is whether individuals with the PrP-129VV/MV genotypes are also resistant to the classical CWD strain and whether humans are resistant to all natural or adapted cervid prion strains. Here we report that a human prion strain that had adopted the cervid prion protein (PrP) sequence through passage in cervidized transgenic mice efficiently infected transgenic mice expressing human PrP, indicating that the species barrier from cervid to humans is prion strain-dependent and humans can be vulnerable to novel cervid prion strains. Preliminary results on CWD transmission in transgenic mice expressing human PrP-129V will also be discussed.

Prion diseases are infectious neurodegenerative disorders affecting humans and animals that result from the conversion of normal prion protein (PrPC) into the misfolded and infectious prion (PrPSc). Chronic wasting disease (CWD) of cervids is a prion disorder of increasing prevalence within the United States that affects a large population of wild and captive deer and elk. CWD is highly contagious and its origin, mechanism of transmission and exact prevalence are currently unclear. The risk of transmission of CWD to humans is unknown. Defining that risk is of utmost importance, considering that people have been infected by animal prions, resulting in new fatal diseases. To study the possibility that human PrPC can be converted into the infectious form by CWD PrPSc we performed experiments using the Protein Misfolding Cyclic Amplification (PMCA) technique, which mimic in vitro the process of prion replication. Our results show that cervid PrPSc can induce the pathological conversion of human PrPC, but only after the CWD prion strain has been stabilized by successive passages in vitro or in vivo. Interestingly, this newly generated human PrPSc exhibits a distinct biochemical pattern that differs from any of the currently known forms of human PrPSc, indicating that it corresponds to a novel human prion strain. Our findings suggest that CWD prions have the capability to infect humans, and that this ability depends on CWD strain adaptation, implying that the risk for human health progressively increases with the spread of CWD among cervids.
PPo2-7:
Biochemical and Biophysical Characterization of Different CWD Isolates
Martin L. Daus and Michael Beekes Robert Koch Institute; Berlin, Germany
Key words: CWD, strains, FT-IR, AFM
Chronic wasting disease (CWD) is one of three naturally occurring forms of prion disease. The other two are Creutzfeldt-Jakob disease in humans and scrapie in sheep. CWD is contagious and affects captive as well as free ranging cervids. As long as there is no definite answer of whether CWD can breach the species barrier to humans precautionary measures especially for the protection of consumers need to be considered. In principle, different strains of CWD may be associated with different risks of transmission to humans. Sophisticated strain differentiation as accomplished for other prion diseases has not yet been established for CWD. However, several different findings indicate that there exists more than one strain of CWD agent in cervids. We have analysed a set of CWD isolates from white-tailed deer and could detect at least two biochemically different forms of disease-associated prion protein PrPTSE. Limited proteolysis with different concentrations of proteinase K and/or after exposure of PrPTSE to different pH-values or concentrations of Guanidinium hydrochloride resulted in distinct isolate-specific digestion patterns. Our CWD isolates were also examined in protein misfolding cyclic amplification studies. This showed different conversion activities for those isolates that had displayed significantly different sensitivities to limited proteolysis by PK in the biochemical experiments described above. We further applied Fourier transform infrared spectroscopy in combination with atomic force microscopy. This confirmed structural differences in the PrPTSE of at least two disinct CWD isolates. The data presented here substantiate and expand previous reports on the existence of different CWD strains.

ADAPTATION OF CHRONIC WASTING DISEASE (CWD) INTO HAMSTERS, EVIDENCE OF A WISCONSIN STRAIN OF CWD

The identification and characterization of prion strains is increasingly important for the diagnosis and biological definition of these infectious pathogens. Although well-established in scrapie and, more recently, in BSE, comparatively little is known about the possibility of prion strains in chronic wasting disease (CWD), a disease affecting free ranging and captive cervids, primarily in North America. We have identified prion protein variants in the white-tailed deer population and demonstrated that Prnp genotype affects the susceptibility/disease progression of white-tailed deer to CWD agent. The existence of cervid prion protein variants raises the likelihood of distinct CWD strains. Small rodent models are a useful means of identifying prion strains. We intracerebrally inoculated hamsters with brain homogenates and phosphotungstate concentrated preparations from CWD positive hunter-harvested (Wisconsin CWD endemic area) and experimentally infected deer of known Prnp genotypes. These transmission studies resulted in clinical presentation in primary passage of concentrated CWD prions. Subclinical infection was established with the other primary passages based on the detection of PrPCWD in the brains of hamsters and the successful disease transmission upon second passage. Second and third passage data, when compared to transmission studies using different CWD inocula (Raymond et al., 2007) indicate that the CWD agent present in the Wisconsin white-tailed deer population is different than the strain(s) present in elk, mule-deer and white-tailed deer from the western United States endemic region.

Molecular characterization of BSE in Canada
Jianmin Yang1, Sandor Dudas2, Catherine Graham2, Markus Czub3, Tim McAllister1, Stefanie Czub1 1Agriculture and Agri-Food Canada Research Centre, Canada; 2National and OIE BSE Reference Laboratory, Canada; 3University of Calgary, Canada
Background: Three BSE types (classical and two atypical) have been identified on the basis of molecular characteristics of the misfolded protein associated with the disease. To date, each of these three types have been detected in Canadian cattle.
Objectives: This study was conducted to further characterize the 16 Canadian BSE cases based on the biochemical properties of there associated PrPres. Methods: Immuno-reactivity, molecular weight, glycoform profiles and relative proteinase K sensitivity of the PrPres from each of the 16 confirmed Canadian BSE cases was determined using modified Western blot analysis.
Results: Fourteen of the 16 Canadian BSE cases were C type, 1 was H type and 1 was L type. The Canadian H and L-type BSE cases exhibited size shifts and changes in glycosylation similar to other atypical BSE cases. PK digestion under mild and stringent conditions revealed a reduced protease resistance of the atypical cases compared to the C-type cases. N terminal- specific antibodies bound to PrPres from H type but not from C or L type. The C-terminal-specific antibodies resulted in a shift in the glycoform profile and detected a fourth band in the Canadian H-type BSE.
Discussion: The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. It also suggests a similar cause or source for atypical BSE in these countries.

Session: International Scientific Exchange
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.
http://ww2.isid.org/Downloads/14th_ICID_ISE_Abstracts.pdf
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.

Taipei, Dec. 18 (CNA) The first probable human case of mad cow disease in Taiwan was listed posthumously Saturday, following the death in May of a man who had symptoms of the fatal brain-wasting illness.
The listing was made after officials and experts on a Department of Health (DOH) panel on Creutzfeldt-Jakob Disease (CJD) held a meeting to determine whether the man had died from the disease as result of eating infected beef.
"We believe it is very likely that the man who died in May this year contracted the disease during his stay in the United Kingdom, " the DOH said in a press statement. "We cannot rule out the possibility that he ate infected beef during that time."
Scientists believe that many years after eating cattle infected with bovine spongiform encephalopathy (BSE) , commonly known as mad cow disease, humans can develop symptoms of new variant CJD (vCJD) , also known as human mad cow disease.
The 36-year-old man had lived in the U.K. between 1989 and 1997, when mad cow disease was at its peak in that country. He began to show vCJD symptoms, including memory loss and hypersomnia, in 2008. Doctors reported the case to the DOH's Centers for Disease Control in March 2009.
As his family refused to give doctors permission to perform an autopsy, the DOH said, it could not list the patient as a confirmed case of vCJD. His body has since been cremated.
Though the cause of death could not be determined by means of an autopsy, it was an extremely likely case of vCJD, based on the man's symptoms, travel history and the results of magnetic resonance imaging and electroencephalograms, the DOH said.
According to the DOH's CJD advisory panel, it was unlikely that the patient contracted the disease in Taiwan.
"His death could be counted as an imported case of vCJD and unlikely to pose any threat to Taiwan's disease control network," the DOH statement said.
Citing its tracking records, the DOH said the man had donated blood to two patients 10 years ago.
"Neither of them has contracted the disease," the statement said, adding that precautionary measures had been taken to prevent any spread of the disease during the time the man was hospitalized in Taiwan.
According to the World Health Organization, CJD is a fatal human degenerative condition characterized by progressive brain dysfunction and is categorized into four forms -- sporadic, familial, iatrogenic and variant.
The UK Department of Health has said vCJD differs from CJD in that the former is more likely to strike younger people.
Since 1997 when the DOH set up a CJD reporting and monitoring system, 436 suspected CJD or vCJD have been reported in Taiwan, DOH figures show. Of that number, 246 were listed as possible or extremely possible cases of sporadic or familial forms of CJD, five were confirmed as traditional forms of CJD and one was listed as probable vCJD, according to the DOH tallies.
The others were ruled out as possible cases of CJD.

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

RURAL AND REGIONAL AFFAIRS AND TRANSPORT
[9.03 am]
BELLINGER, Mr Brad, Chairman, Australian Beef Association
CARTER, Mr John Edward, Director, Australian Beef Association
CHAIR—Welcome. Would you like to make an opening statement?
Mr Bellinger—Thank you. The ABA stands by its submission, which we made on 14 December last year, that the decision made by the government to allow the importation of beef from BSE affected countries is politically based, not science based. During this hearing we will bring forward compelling new evidence to back up this statement. When I returned to my property after the December hearing I received a note from an American citizen. I will read a small excerpt from the mail he sent me in order to reinforce the dangers of allowing the importation of beef from BSE affected countries. I have done a number of press releases on this topic, and this fellow has obviously picked my details up from the internet. His name is Terry Singeltary and he is from Bacliff, Texas. He states, and rightfully so:
You should be worried. Please let me explain. I’ve kept up with the mad cow saga for 12 years today, on December 14th 1997, some four months post voluntary and partial mad cow feed ban in the USA, I lost my mother to the Heidenhain variant Creutzfeldt-Jakob disease (CJD). I know this is just another phenotype of the infamous sporadic CJDs. Here in the USA, when USA sheep scrapie was transmitted to USA bovine, the agent was not UK BSE—it was a different strain. So why then would human TSE from USA cattle look like UK CJD from UK BSE? It would not. So this accentuates that the science is inconclusive still on this devastating disease. He goes on to state:
The OIE— the International Organisation of Epizootics, the arm of the WTO— is a failed global agent that in my opinion is bought off via bogus regulations for global trade and industry reps. I have done this all these years for nothing but the truth. I am a consumer, I eat meat, but I do not have to sit idly by and see the ignorance and greed of it all while countless numbers of humans and animals are being exposed to the TSE agents. All the USA is interested in is trade, nothing else matters.
Even Dr Stanley Prusiner, who incidentally won the Nobel Health Prize in 1997 for his work on the prion—he invented the word ‘prion’, or it came from him—states:
The BSC policy was set up for one purpose only, trade—the illegal trading of all strains of TSE globally throughout North America, which is home to CBSC, IBSC and HBSC, many scrapie strains and two strains of CJD to date. (please note typo error, those should have read cBSE, lBSE, and hBSE...tss)
I would also like, while I have the opportunity, to explain the beef-off-the-shelves myth. At the first Senate hearing on 14 December, it was explained that the reason why they allowed BSC beef into Australia was the beef-off-the-shelves policy, whereby if we found a case of BSC in Australia they would have to recall all—

RURAL AND REGIONAL AFFAIRS AND TRANSPORT
Senator HEFFERNAN—Which of course is total BS.
Mr Bellinger—Correct. This is written in the FSANZ document—Food Standards Australia New Zealand. Why isn’t this same policy in New Zealand? It is not—it is only in Australia. We are the only country in the world to have this idiotic policy. So we again call for the tabling of the WTO obligations paperwork. We do not believe that exists.

Through the internet, many people here in Korea have learnt about the story of your family and it has created a great deal of concern. Your experience had particular relevance for the citizens here, for the Korean government, in connection to the free trade agreement it is negotiating with the United States, is about to restart the sale of the unsafe American beef to the general public.
The Korean government has already imported the first load American beef and is currently going through the inspection period. There has been a great deal of controversy regarding the safety of these products, and a precipitous increase in public interest regarding the causes and symptoms of vCJD.
It is in this context that we are preparing a session together with National Assembly members and relevant NGOs to hear from those who have had direct experience with the human variant of BSE. We are very interested in hearing about the symptoms that your mother showed, your views on the response from the US government to the many deaths that resulted from this disease, the reaction from the general public, and any other area that you would wish to speak about. There would also be experts and academics in the area to speak at the session as well. We believe that it would greatly contribute to raising awareness about the issue, as well as help politicians and civic activists to consider the repercussions of the beef import issue.
We would like to request your help in this regard. We are planning for the session to be held in Seoul on the 23rd of this November. We would very much like to have you present in order to help prevent such tragic incidents from happening in Korea. We would, of course, pay for the trip and accommodations for the duration of your stay. If you were to participate, we could also meet with members from the agricultural committee of the National Assembly and from other related organizations to urge more interest to the issue.
Please do not hesitate to offer suggestions or ask us any questions that you might have. We look forward to a positive response and to meeting you in Seoul.
Thank you.
Sincerely, Sim Sang-Jeong
Head of the Democratic Labor Party Parliamentary Committee on the Korea-US FTA Member of the National Assembly Republic of Korea

Comment 2006-2007 USA AND OIE POISONING GLOBE WITH BSE MRR POLICY
THE USA is in a most unique situation, one of unknown circumstances with human and animal TSE. THE USA has the most documented TSE in different species to date, with substrains growing in those species (BSE/BASE in cattle and CWD in deer and elk, there is evidence here with different strains), and we know that sheep scrapie has over 20 strains of the typical scrapie with atypical scrapie documented and also BSE is very likely to have passed to sheep. all of which have been rendered and fed back to animals for human and animal consumption, a frightening scenario. WE do not know the outcome, and to play with human life around the globe with the very likely TSE tainted products from the USA, in my opinion is like playing Russian roulette, of long duration, with potential long and enduring consequences, of which once done, cannot be undone. These are the facts as I have come to know through daily and extensive research of TSE over 9 years, since 12/14/97. I do not pretend to have all the answers, but i do know to continue to believe in the ukbsenvcjd only theory of transmission to humans of only this one strain from only this one TSE from only this one part of the globe, will only lead to further failures, and needless exposure to humans from all strains of TSE, and possibly many more needless deaths from TSE via a multitude of proven routes and sources via many studies with primates and rodents and other species.
MY personal belief, since you ask, is that not only the Canadian border, but the USA border, and the Mexican border should be sealed up tighter than a drum for exporting there TSE tainted products, until a validated, 100% sensitive test is available, and all animals for human and animal consumption are tested. all we are doing is the exact same thing the UK did with there mad cow poisoning when they exported it all over the globe, all the while knowing what they were doing. this BSE MRR policy is nothing more than a legal tool to do just exactly what the UK did...

Descripción: Transmission of prions between mammalian species is thought to be limited by a "species barrier," which depends on differences in the primary structure of prion proteins in the infecting inoculum and the host, Here we demonstrate that a strain of hamster prions thought to be nonpathogenic for conventional mice leads to prion replication to high levels in such mice but without causing clinical disease. Prions pathogenic in both mice and hamsters are produced. These results demonstrate the existence of subclinical forms of prion infection with important public health implications, both with respect to iatrogenic transmission from apparently healthy humans and dietary exposure to cattle and other species exposed to bovine spongiform encephalopathy prions, Current definitions of the species barrier, which have been based on clinical endpoints, need to be fundamentally reassessed.

Increased susceptibility of human-PrP transgenic mice to bovine spongiform encephalopathy following passage in sheep
http://bse-atypical.blogspot.com/2010/11/increased-susceptibility-of-human-prp.html
Seven main threats for the future linked to prions
The NeuroPrion network has identified 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.

Dear Sir/Madam, 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." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.

There are now two documented strains of CWD, and science is showing that indeed CWD could transmit to humans via transmission studies ;

Prion Transmission from Cervids to Humans is Strain-dependent

Key words: CWD, strain, human transmission
Chronic wasting disease (CWD) is a widespread prion disease in cervids (deer and elk) in North America where significant human exposure to CWD is likely and zoonotic transmission of CWD is a concern. Current evidence indicates a strong barrier for transmission of the classical CWD strain to humans with the PrP-129MM genotype. A few recent reports suggest the presence of two or more CWD strains. What remain unknown is whether individuals with the PrP-129VV/MV genotypes are also resistant to the classical CWD strain and whether humans are resistant to all natural or adapted cervid prion strains. Here we report that a human prion strain that had adopted the cervid prion protein (PrP) sequence through passage in cervidized transgenic mice efficiently infected transgenic mice expressing human PrP, indicating that the species barrier from cervid to humans is prion strain-dependent and humans can be vulnerable to novel cervid prion strains. Preliminary results on CWD transmission in transgenic mice expressing human PrP-129V will also be discussed.

Generation of a Novel form of Human PrPSc by Inter-species Transmission of Cervid Prions

Prion diseases are infectious neurodegenerative disorders affecting humans and animals that result from the conversion of normal prion protein (PrPC) into the misfolded and infectious prion (PrPSc). Chronic wasting disease (CWD) of cervids is a prion disorder of increasing prevalence within the United States that affects a large population of wild and captive deer and elk. CWD is highly contagious and its origin, mechanism of transmission and exact prevalence are currently unclear. The risk of transmission of CWD to humans is unknown. Defining that risk is of utmost importance, considering that people have been infected by animal prions, resulting in new fatal diseases. To study the possibility that human PrPC can be converted into the infectious form by CWD PrPSc we performed experiments using the Protein Misfolding Cyclic Amplification (PMCA) technique, which mimic in vitro the process of prion replication. Our results show that cervid PrPSc can induce the pathological conversion of human PrPC, but only after the CWD prion strain has been stabilized by successive passages in vitro or in vivo. Interestingly, this newly generated human PrPSc exhibits a distinct biochemical pattern that differs from any of the currently known forms of human PrPSc, indicating that it corresponds to a novel human prion strain. Our findings suggest that CWD prions have the capability to infect humans, and that this ability depends on CWD strain adaptation, implying that the risk for human health progressively increases with the spread of CWD among cervids.
PPo2-7:
Biochemical and Biophysical Characterization of Different CWD Isolates
Martin L. Daus and Michael Beekes Robert Koch Institute; Berlin, Germany
Key words: CWD, strains, FT-IR, AFM
Chronic wasting disease (CWD) is one of three naturally occurring forms of prion disease. The other two are Creutzfeldt-Jakob disease in humans and scrapie in sheep. CWD is contagious and affects captive as well as free ranging cervids. As long as there is no definite answer of whether CWD can breach the species barrier to humans precautionary measures especially for the protection of consumers need to be considered. In principle, different strains of CWD may be associated with different risks of transmission to humans. Sophisticated strain differentiation as accomplished for other prion diseases has not yet been established for CWD. However, several different findings indicate that there exists more than one strain of CWD agent in cervids. We have analysed a set of CWD isolates from white-tailed deer and could detect at least two biochemically different forms of disease-associated prion protein PrPTSE. Limited proteolysis with different concentrations of proteinase K and/or after exposure of PrPTSE to different pH-values or concentrations of Guanidinium hydrochloride resulted in distinct isolate-specific digestion patterns. Our CWD isolates were also examined in protein misfolding cyclic amplification studies. This showed different conversion activities for those isolates that had displayed significantly different sensitivities to limited proteolysis by PK in the biochemical experiments described above. We further applied Fourier transform infrared spectroscopy in combination with atomic force microscopy. This confirmed structural differences in the PrPTSE of at least two disinct CWD isolates. The data presented here substantiate and expand previous reports on the existence of different CWD strains.

ADAPTATION OF CHRONIC WASTING DISEASE (CWD) INTO HAMSTERS, EVIDENCE OF A WISCONSIN STRAIN OF CWD
Chad Johnson1, Judd Aiken2,3,4 and Debbie McKenzie4,5 1 Department of Comparative Biosciences, University of Wisconsin, Madison WI, USA 53706 2 Department of Agriculture, Food and Nutritional Sciences, 3 Alberta Veterinary Research Institute, 4.Center for Prions and Protein Folding Diseases, 5 Department of Biological Sciences, University of Alberta, Edmonton AB, Canada T6G 2P5
The identification and characterization of prion strains is increasingly important for the diagnosis and biological definition of these infectious pathogens. Although well-established in scrapie and, more recently, in BSE, comparatively little is known about the possibility of prion strains in chronic wasting disease (CWD), a disease affecting free ranging and captive cervids, primarily in North America. We have identified prion protein variants in the white-tailed deer population and demonstrated that Prnp genotype affects the susceptibility/disease progression of white-tailed deer to CWD agent. The existence of cervid prion protein variants raises the likelihood of distinct CWD strains. Small rodent models are a useful means of identifying prion strains. We intracerebrally inoculated hamsters with brain homogenates and phosphotungstate concentrated preparations from CWD positive hunter-harvested (Wisconsin CWD endemic area) and experimentally infected deer of known Prnp genotypes. These transmission studies resulted in clinical presentation in primary passage of concentrated CWD prions. Subclinical infection was established with the other primary passages based on the detection of PrPCWD in the brains of hamsters and the successful disease transmission upon second passage. Second and third passage data, when compared to transmission studies using different CWD inocula (Raymond et al., 2007) indicate that the CWD agent present in the Wisconsin white-tailed deer population is different than the strain(s) present in elk, mule-deer and white-tailed deer from the western United States endemic region.

Molecular characterization of BSE in Canada
Jianmin Yang1, Sandor Dudas2, Catherine Graham2, Markus Czub3, Tim McAllister1, Stefanie Czub1 1Agriculture and Agri-Food Canada Research Centre, Canada; 2National and OIE BSE Reference Laboratory, Canada; 3University of Calgary, Canada
Background: Three BSE types (classical and two atypical) have been identified on the basis of molecular characteristics of the misfolded protein associated with the disease. To date, each of these three types have been detected in Canadian cattle.
Objectives: This study was conducted to further characterize the 16 Canadian BSE cases based on the biochemical properties of there associated PrPres. Methods: Immuno-reactivity, molecular weight, glycoform profiles and relative proteinase K sensitivity of the PrPres from each of the 16 confirmed Canadian BSE cases was determined using modified Western blot analysis.
Results: Fourteen of the 16 Canadian BSE cases were C type, 1 was H type and 1 was L type. The Canadian H and L-type BSE cases exhibited size shifts and changes in glycosylation similar to other atypical BSE cases. PK digestion under mild and stringent conditions revealed a reduced protease resistance of the atypical cases compared to the C-type cases. N terminal- specific antibodies bound to PrPres from H type but not from C or L type. The C-terminal-specific antibodies resulted in a shift in the glycoform profile and detected a fourth band in the Canadian H-type BSE.
Discussion: The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. It also suggests a similar cause or source for atypical BSE in these countries.

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.

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.
