Mo' Bob - Let me first state that I sympathize with your loss....It seems if you have had a really rough period over the last few weeks... While I read your note on your latest outbreak, I became concerned because the syndrome you describe does not really correspond to that of proliferative colitis, at least not what I have seen. I Proliferative colitis is not an epidemic disease, but a sporadic one, and one which tends to last for weeks or even months before death occurs. I have never heard of a case where 50% of the animals in a household were affected. It results in profound straining and passage of small often bloody stools, not watery greenish stools. I'm not sure what to make of the positive diagnosis of campylobacter - in most cases of proliferative colitis, the campylobacter (actually we know that it's not campylobacter but a related bacteria named Lawsonia (Ileobacter) now) is not isolated. How was it isolated so quickly? I would be interested in seeing the slides from this case, if you wouldn't mind a second opinion. Hang in there with all of the rest....
