From what I saw of the press conference, that's what's so stunning about Dr. Bastion's research at LSU. TSEs and CWD have been his research specialty for years. Most everyone researching the topic thought CWD was caused by prions, but now it seems the prions are a by-product of the CWD, not the cause. At least that's what his experiments are suggesting.Not so sure about the previously unknown bacterium. If that's the case, antibiotics would cure a deer. Most researchers have said it's cause by prions where there isn't any cure.
