Is this true? Tomorrow I get the >meds and get to work again on all of them. First off, if it truly coccidia (you would think that a university wouldn't have any problem, but I have seen a lot of normal yeasts misdiagnosed as coccidia), then the theory of getting it from birds, trees, dogs, cats, etc. is not a viable one. Coccidia are fairly species-specific, and ferret will only pick up coccidia from other mustelids. Now they may ingest oocysts from other species, such as dogs and cats, which will come out in the stool, but do not set up a propagating infection. Remember that the oocyst (infective egg) stage of the coccidia (Yes, they ARE protozoa.) can live outside the body for quite a while, and resists drying. They can get in cracks and crevices of cages, etc. and bide their time until ingested by a naive ferret, and the cycle starts over again. This is more likely than coccidia living on in the intestine of a treated ferret. And, most coccidia outbreaks have more than one affected animal....
