Scrapie is a fatal, degenerative disease affecting the nervous systems of sheep and goats. It is one of several transmissible spongiform encephalopathies (TSEs), and as such it is thought to be caused by a prion.
Scrapie and other transmissible spongiform encephalopathies are caused by prion disease.
