Hi All, Yesterday I brought my 1.5 year old Chinese water dragon to the vet for a check-up, x-ray and stool sample examination. Everything is OK with the lizard - good coloration, no problems with the bones, eyes, etc. In short - he is very healthy, according to the vet. Today I received the results from the stool sample: Fecal test results for water dragon: Sample from water, refrigerated. Direct smear: ++(+) positive; flagellated protozoa. Fuelleborn Flotation: - , negative What the lab lady told me over the phone was that the number of protozoa was a low one and it is very possible that the bacteria comes from the water in which the lizard defecated ( a large heated pool in his terrarium), rather than his intestines. I'll take him to the vet for a more thorough examination in a few months, as if I understood correctly, there is no cause for alarm at this moment. Meanwhile, I'll monitor his appetite, growth rate, etc. My question is has this happened to your reptile and do you have any advice for me? Is there any way to treat the water in order to eliminate the bacteria? The water is filtered, but it seem that that's not enough... Thank you!
