My Buck has had diarrhea for a while now, I had a fecal done on him and he came back with coccidia so I treated him for that and also de-wormed him with ivromecitn orally and then I lated gave him an injection as well. It has still not gone away and I ran another fecal and it was clean. I was just wondering if it could be possible that he might have Johnes. It is perfectly heathly otherwise, he is not thin, no loss of appetite, is acts normal in every other way but the diarrhea. Does anyone have any ideas?
