Oral Transmission of L-type Bovine Spongiform Encephalopathy in Primate Model

We report transmission of atypical L-type bovine spongiform encephalopathy to mouse lemurs after oral or intracerebral inoculation with infected bovine brain tissue. After neurologic symptoms appeared, transmissibility of the disease by both inoculation routes was confirmed by detection of disease-associated prion protein in samples of brain tissue.

Bovine Spongiform Encephalopathy A Review of the Scientific Literature

Sacred disease of our times: failure of the infectious disease model of spongiform encephalopathy.

BACKGROUND Public health and agricultural policy attempts to keep bovine spongiform encephalopathy out of North America using infectious disease containment policies. Inconsistencies of the infectious disease model as it applies to the spongiform encephalopathies may result in failure of these policies. METHODS Review of historical, political and scientific literature to determine the appropr...

Molecular Discrimination of Sheep Bovine Spongiform Encephalopathy from Scrapie

Sheep CH1641-like transmissible spongiform encephalopathy isolates have shown molecular similarities to bovine spongiform encephalopathy (BSE) isolates. We report that the prion protein PrPSc from sheep BSE is extremely resistant to denaturation. This feature, combined with the N-terminal PrPSc cleavage, allowed differentiation of classical scrapie, including CH1641-like, from natural goat BSE ...

How now mad cow?

Since the BM7's last editorial on the topic' another 40 000 cases of bovine spongiform encephalopathy have been confirmed in cattle. New cases are being confirmed at the rate of 500 a week. Does it matter that between 1986 and 1989 we actually had the offal, which is now proscribed, going into the food chain?2 Several reasons are given for dismissing bovine spongiform encephalopathy as carrying...
