NEW BRAIN DISORDER
3. WHAT ABOUT REPORTS OF NEW FORM OF BSE?
THE VETERINARY RECORD HAS PUBLISHED AN ARTICLE ON A NEW BRAIN DISORDER OF CATTLE DISCOVERED THROUGH OUR CONTROL MEASURES FOR BSE. ALTHOUGH IT PRESENTS SIMILAR CLINICAL SIGNS TO BSE THERE ARE MAJOR DIFFERENCES IN THE HISTOPATHOLOGY AND INCUBATION PERIODS BETWEEN THE TWO. MUST EMPHASISE THAT THIS IS NOT BSE.
4. IS THIS NEW BRAIN DISORDER A THREAT?
WE DO NOT EVEN KNOW WHETHER THE AGENT OF THIS DISEASE IS TRANSMISSIBLE. IN ANY CASE, CASES SO FAR IDENTIFIED HAD SHOWN SIMILAR SYMPTOMS TO THOSE OF BSE, AND THEREFORE HAVE BEEN SLAUGHTERED AND INCINERATED, SO THAT IF A TRANSMISSIBLE AGENT WERE INVOLVED IT WOULD HAVE BEEN ELIMINATED. .......

2. The Collinge/Will dispute appears to rumble on. Dr. Collinge had told Dr. Tyrrell that Dr. Will's response to his criticism about sharing material had been ''quite unacceptable'' (in spite of it's apparently conciliatory tone). Apparently Professor Allen was now going to try and arrange a meeting to resolve the dispute. No action here for MAFF, although Mr. Murray may be interested.
3. Dr. Tyrrell regretted that the Committee had not seen the article on BBD. However he felt that for the time being NO specific action was called for. The most important need was to consider the possibility that the condition might be transmissible. As we have discussed, I suggested that we might circulate a paper to the members of the committee giving our appreciation of this condition (and perhaps of other non-BSE neurological conditions that had been identified in negative cases) and of any necessary follow up action. IF any Committee member felt strongly about this, or if the issue CAME TO A HEAD, we would call an interim meeting. He was happy with this approach. I would be grateful if Mr. Maslin could, in discussion with CVL and veterinary colleagues draft such a note, which will presumably very largely follow what Mr. Bradley's briefing paper has already said, taking account of DOH comments, We can then clear a final version with DOH before circulating it to Committee members.

IN CONFIDENCE
This is a highly competitive field and it really will be a pity if we allow many of the key findings to be published by overseas groups while we are unable to pursue our research findings because of this disagreement, which I hope we can make every effort to solve.

2. The discovery might indicate the existence of a different strain of BSE from that present in the general epidemic or an unusual response by an individual host.
3. If further atypical lesion distribution cases are revealed in this herd then implications of misdiagnosis of 'negative' cases in other herds may not be insignificant.

USA ATYPICAL BSE STRAIN MORE VIRULENT TO HUMANS THAN UK BSE STRAIN

64. A member noted that at the recent Neuroprion meeting, a study was
presented showing that in transgenic mice BSE passaged in sheep may be more
virulent and infectious to a wider range of species than bovine derived BSE.
Other work presented suggested that BSE and bovine amyloidotic spongiform
encephalopathy (BASE) MAY BE RELATED. A mutation had been identified in the
prion protein gene in an AMERICAN BASE CASE THAT WAS SIMILAR IN NATURE TO A
MUTATION FOUND IN CASES OF SPORADIC CJD.

Models Qingzhong Kong, Ph.D., Assistant Professor, Pathology, Case Western Reserve
University
Bovine Amyloid Spongiform Encephalopathy (BASE) is an atypical BSE strain
discovered recently in Italy, and similar or different atypical BSE cases
were also reported in other countries. The infectivity and phenotypes of
these atypical BSE strains in humans are unknown. In collaboration with
Pierluigi Gambetti, as well as Maria Caramelli and her co-workers, we have
inoculated transgenic mice expressing human prion protein with brain
homogenates from BASE or BSE infected cattle. Our data shows that about half
of the BASE-inoculated mice became infected with an average incubation time
of about 19 months; in contrast, none of the BSE-inoculated mice appear to
be infected after more than 2 years.
***These results indicate that BASE is transmissible to humans and suggest that BASE is more virulent than
classical BSE in humans.***

of 'UNKNOWN' strain growing. ...
http://www.cjdsurveillance.com/resource ... eport.html
There is a growing number of human CJD cases, and they were presented last
week in San Francisco by Luigi Gambatti(?) from his CJD surveillance
collection.
He estimates that it may be up to 14 or 15 persons which display selectively
SPRPSC and practically no detected RPRPSC proteins.
