I have a question about BSE that perhaps someone could answer. The
theory is that the scrapie agent has somehow mutated and changed into a
form that infects cattle and other mammals, such as cats. Cattle
infected with the BSE agent can start to show symptoms within a couple
of years. Why then is it that the same mutated scrapie agent is not
expected to cause symptoms in humans for 20-30 years ?
