[1] It is one of several transmissible spongiform encephalopathies (TSEs), and as such it is thought to be caused by a prion. [2] [3] Scrapie has been known since at least 1732 and does not appear to be transmissible to humans.
Scrapie – a wasting disease of sheep and goats, a transmissible spongiform encephalopathy (TSE, like BSE of cattle) and believed to be caused by a prion.

TSEs in non-human mammals include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle – popularly known as "mad cow disease" – and chronic wasting disease (CWD) in deer and elk. The variant form of Creutzfeldt–Jakob disease in humans is caused by exposure to bovine spongiform encephalopathy prions. [4] [5] [6]
