Re: plague
Edd,
I have commented before that I am a veterinarian and a board certified pathologist. I do not examine fish very often in the course of my "paid job". However, being an aquarist I sometimes do study my own fish microscopically if I want to clarify the cause of a disease and I sometimes do it for follow members of the hobby. There are real costs to processing tissues for histopathology, hence my comment that the procedure costs about $25. I should add the disclaimer that, although we can often provide and answer, there are no guarantees. Not all diseases produce characteristic microscopic changes.
Bob Goldstein is, I believe, a Ph.D. parasitologist. Correct me if I'm wrong please Bob.
