Animal Transmissible Spongiform Encephalopathies (TSEs)

TSEs that occur in animals include scrapie of sheep and goats, transmissible mink encephalopathy, chronic wasting disease of deer and elk, and bovine spongiform encephalopathy (also known as "mad cow" disease).

• Bovine Spongiform Encephalopathy (BSE)
  Bovine spongiform encephalopathy (BSE) is a fatal neurodegenerative brain disorder affecting cattle that is believed to be caused by abnormally folded proteins called prions.
  
  
• Chronic Wasting Disease (CWD)
  Chronic wasting disease (CWD) is a fatal brain disease found in deer and elk in certain parts of North America. CWD is believed to be caused by abnormally folded proteins called prions. CWD is not thought to be transmissible to humans.
  
  
• Scrapie
  Scrapie is a fatal neurodegenerative brain disorder caused by a prion affecting sheep and goats.
  
  
• Transmissible mink encephalopathy
  Transmissible mink encephalopathy is a rare neurodegenerative brain disorder caused by a prion found in mink.
  
  
• Feline spongiform encephalopathy
  Feline spongiform encephalopathy is a rare neurodegenerative brain disorder caused by a prion found in members of the cat family.
  
  
• Ungulate spongiform encephalopathy
  Ungulate spongiform encephalopathy is a rare neurodegenerative brain disorder caused by a prion found in mammals with hooves.
