How it is transferred from animal to animal, and animal to human is still not yet well understood. The theory that is most currently probable is that the disease is transferred by an abnormal protein known as a prion protein and then consumed (CDC). This disease causes tiny holes in the brain that when looked at under a microscope the brain appears to be spongy (NINDS). These holes are causes by the abnormal protein that were consumed. Below is a picture of two human brains; QuickTime and a TIFF (Uncompressed) decompressor are needed to see this picture. the left side is the brain of a person who died from Mad Cow Disease, and the brain on the right is from a healthy deceased person (NINDS). You can see the obvious shrikage of the brain itself, and how the solid parts look as if they are not as dense as the healthy 1
