What Is Mad Cow Disease and Variant Creutzfeldt-Jakob Disease? Mad cow disease is an infectious disease caused by prions that affect the brains of cattle. The actual name of the disease is bovine spongiform encephalopathy (BSE), a name that refers to the changes seen in brain tissue of affected cows.
Cause of the Mad Cow Disease. The mad cow disease is considered associated to modification or conformational change of a normal cell surface protein called prion protein. The reasons for this conformational change are still unknown. This disease is incurable and fatal in cattle. The infected cattle lose the ability to perform normal actions such as standing or walking, and hence, the disease derives its name of mad cow. The disease severely affects the nervous system of cattle, including the brain and spinal cord.
