Scrapie is a neurodegenerative disease, caused by a prion, that affects sheep and occasionally goats. In sheep, the animal’s genotype strongly influences the incidence of disease. Genetically susceptible sheep do not become ill for several years; however, scrapie is progressive and fatal once the symptoms develop.
