Experimental infection of spongiform encephalopathy cattle in goats

Experimental interspecies transmission studies of the transmissible spongiform encephalopathies to cattle: comparison to bovine spongiform encephalopathy in cattle.

Prion diseases or transmissible spongiform encephalopathies (TSEs) of animals include scrapie of sheep and goats; transmissible mink encephalopathy (TME); chronic wasting disease (CWD) of deer, elk and moose; and bovine spongiform encephalopathy (BSE) of cattle. The emergence of BSE and its spread to human beings in the form of variant Creutzfeldt-Jakob disease (vCJD) resulted in interest in su...

Surveillance for lesions of bovine spongiform encephalopathy in US cattle.

The appearance of bovine spongiform encephalopathy (BSE) as a new disease of cattle in 1985-1987 increased worldwide interest in various aspects of human and animal spongiform encephalopathies. In the United States, a part of the surveillance effort has been directed toward prospective examination of bovine brain specimens for lesions of BSE. One focus area has been to obtain specimens from cat...

Prion in Saliva of Bovine Spongiform Encephalopathy–Infected Cattle

To the Editor: A defi nitive diagnosis of bovine spongiform encephalopathy (BSE) in cattle usually relies on Western blot and immunohistochemical testing of samples from the obex region of the brainstem. These conventional diagnostic tests can detect the presence of the abnormal (disease-associated) form of the prion protein (PrPSc) in brain samples several months before the onset of clinical s...

Case Report of Encephalopathy in Goats

Natural and experimental oral infection of nonhuman primates by bovine spongiform encephalopathy agents.

Experimental lemurs either were infected orally with the agent of bovine spongiform encephalopathy (BSE) or were maintained as uninfected control animals. Immunohistochemical examination for proteinase-resistant protein (prion protein or PrP) was performed on tissues from two infected but still asymptomatic lemurs, killed 5 months after infection, and from three uninfected control lemurs.
