Résumé :
|
Bovine spongiform encephalopathy (BSE) is a fatal neurological disease of cattle, recognized in Great Britain in 1986. Cases in other countries have been attributed to imports from Great Britain. The disease has not occurred in the U.S. BSE is one of a group of diseases (other examples are scrapie of sheep and Creutzfeld-Jacob disease of humans) referred to as prion diseases or transmissible spongiform encephalopathies. Under some circumstances prion diseases can be transmitted by injection or by feeding infected (abnormal prion protein-containing) tissue to susceptible hosts. BSE was disseminated by feeding meal and bone meal containing BSE agent which was not completely inactivated by rendering, BSE is hypothesized to have emerged from scrapie via recycling of rendered by-products in cattle. There is also evidence of spontaneous feed-borne transmission of BSE to wild ruminants in zoological parks and to domestic cats. It has been hypothesized that foodborne transmission of BSE to humans has occurred or could occur.
