Corelation with the feed ban, or coincidence. Why are there still cases being discovered after the feed ban? Lots in the UK and more coming all over the world when the world finally does test transperently and with diligent numbers.

Mark's theory has not changed. Unlike the simple theory of injestion that everyone seems to follow, BSE is a complex chemical (metal imbalance) problem. Why would it not seem reasonable that OP's could upset the chemical balance in a mammal, and along with any other number of factors bring on a situation like BSE? Why does the prion misfold reader(the second)? Does the conventional theory have a position yet, or is it still the unknown factorX?

Last but not least Kathy and I have mentioned time and again the homoginate process used in the oral injestion of lab mice etc. This process of homoginization could very well release the metals attached to the misfolded prion and overbear the new host with heavy metal contamination causing the same problem, but not supporting infection. Sure it's just a theory, but to make a theory into proven fact, the claim of oral infection should have to prove alternates wrong, should it not?
