Editorial: Development of Australia's response to bovine spongiform encephalopathy and variant Creutzfeldt-Jakob disease.
نویسنده
چکیده
Australia has had two historical incidents of animal TSEs. In 1952 an imported herd of sheep was found to have scrapie. The herd was quarantined without any further spread of the infectious agent. In 1991, a cheetah in a zoo in Broome was discovered to have feline spongiform encephalopathy. This incident was attributed to exposure to infected meat and bone meal (MBM), before the animal was imported into Australia.

Variant Creutzfeldt-Jakob disease.
Current evidence indicates that variant Creutzfeldt-Jakob disease is caused by the transmission of bovine spongiform encephalopathy to humans. The clinical and investigative features of variant CJD are relatively distinct from sporadic CJD and the neuropathological appearances are novel. The number of cases of vCJD in the UK may have peaked, but the total future number of cases of vCJD is uncer...
متن کاملAccumulation of prion protein in tonsil and appendix: review of tissue samples.
Variant Creutzfeldt-Jakob disease is almost certainly caused by the bovine spongiform encephalopathy agent, and although the disease is rare (115 deaths to date) there is uncertainty about future numbers of cases. The lack of a conventional immune response and the inability to detect abnormal prion protein in blood has hampered the development of a blood test. Lymphoreticular accumulation of pr...
متن کاملThe new variant of the Creutzfeldt-Jakob disease accounts for no relative increase of the Creutzfeldt-Jakob disease mortality rate in the United Kingdom; this fits ill with the new variant being the consequence of consumption of food infected with the agent of Bovine Spongiform Encephalopathy
BACKGROUND A new variant of Creutzfeldt-Jakob disease was described in the United Kingdom. It is often claimed that it is caused by consumption of food infected with the agent of bovine spongiform encephalopathy. However, this remains open to question because the number of cases of the variant is, at the present time, less than would be expected from a major food-borne source. DISCUSSION The ...

متن کاملNew variant Creutzfeldt-Jakob disease.
New variant Creutzfeldt-Jakob disease is a novel human prion disorder with characteristic clinical and neuropathological features, which results from exposure to the bovine spongiform encephalopathy agent. The probably lengthy incubation period makes it difficult to predict future new variant Creutzfeldt-Jakob disease case numbers; further studies are required to clarify risk factors and the po...
