Other animal prion diseases

In addition to bovine spongiform encephalopathy (BSE) of cattle and scrapie of sheep and goats, a few other animal prion diseases have been reported. These include feline spongiform encephalopathy of zoological and domestic cats (FSE) and transmissible spongiform encephalopathy (TSE) of zoological ruminants and non-human primates, as well as chronic wasting disease of deer and elk (CWD) and transmissible mink encephalopathy of farmed mink (TME). The origins of TSE in cats, zoo bovids, and non-human primates are clearly linked to the BSE epidemic; however, the origins of CWD and TME are less clear, but are not epidemiologically linked to the BSE epidemic. Here we review the epidemiology, transmission, clinical features and pathology of these other animal prion diseases.
