Detailed explanation-1: -BSE also known as Mad Cow Disease is a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion. CWD is a prion disease that affects deer, elk and moose in some areas of North America, South Korea and Norway.

Detailed explanation-2: -Bovine Spongiform Encephalopathy (BSE), or Mad Cow Disease Currently, the most accepted theory is that the agent is a modified form of a normal protein known as prion protein.

Detailed explanation-3: -What causes prion disease? Prion diseases occur when normal prion protein, found on the surface of many cells, becomes abnormal and clump in the brain, causing brain damage. This abnormal accumulation of protein in the brain can cause memory impairment, personality changes, and difficulties with movement.

Detailed explanation-4: -Mad cow disease is a progressive, fatal neurological disorder of cattle resulting from infection by a prion. It appears to be caused by contaminated cattle feed that contains the prion agent.

Detailed explanation-5: -Neurotropic influenza A virus infection causes prion protein misfolding into infectious prions in neuroblastoma cells.
