That's horrible. Mind sharing any more information when you get the chance? For example do any of the other species have it? Or get have they been tested for it? Any new tortoises arrive recently that could have spread it? Did you notice any symptoms?
I echo G-stars sentiments. The more I know of this, the better. Please, share the stories.
Testing is only via PCR at the University of Florida College of Veterinary Medicine Zoo Animal Diagnostic Laboratory. Cloacal Swab is method of choice. Since this is an intranuclear protozoan, regular fecal exam will not identify this species of Eimeria.Treatment is hopeful but expensive. Ponazuril is the drug of choice and current recommendation is 55mg/Kg B.W. daily until 2 negative testes are found. Can take up to a year or longer depending on how many copies are found on PCR. I routinely screen my group just to be sure all is well. And yes, I have to pay for the tests just like everyone else. This is the desired result.
