I have brought him to the Vet twice now and he is slowing going down hill. Had to start force feed/hydrating him because he is so weak. Had one antibiotic run already from the first visit and now starting a second from the visit yesterday and also a deworming treatment. Been checked over thoroughly for mites and none seen. Poop checked for parasites..none. His lungs and heart sound normal and he still has decent strength if he needs it but sadly that is getting weaker by the day. His poop looks normal as it can considering its not much as he isnt eating on his own.(just the small amount of supplement if feed him) I am beyond frustrated at this point. I have had exotics for over 20 years including Macaws, African Greys, other chameleons, to name a few, high maintenance animals. This little guy has me and the Vet stumped. Any ideas ? He isnt going back to the Vet so this may be it.
I know I'm joining in on this thread late, but here are some thoughts to consider. When things don't seem to be adding up, I like to go back to the beginning and look at everything differently. My sense is that you are seeing a combination of compounding stressors on top of the original problem. If he's
throwing up foam there's a chance its NOT actually a respiratory problem but an intestinal one. Deworming treatment is stressful and didn't seem to be necessary, force feeding is stressful (I know, a double edged sword), and possibly the antibiotic the vet gave you isn't addressing what is wrong. Baytril is often prescribed as it a broad spectrum med. However, it is hard on chams and some react badly to it. Its also possible that the bacteria causing the infection (if that's what this is) is not sensitive to Baytril. Did the vet do any sensitivity testing (maybe using the cham's saliva or the foamy discharge)? I am also puzzled by the vet's comment that his lungs sounded normal. If he has a RI this serious wouldn't the lungs sound abnormal? Remember, chams have a system of airsacs similar to birds, and they can develop infections too.
A couple of comments about your description of the humidifier "dust". It is most likely mineral deposit from the evaporated tap water. There is nothing inherently hazardous about the dust, so I really doubt it caused the problem on its own. I suspect your panther would have shown similar problems if that was the cause. And, if it was municipal tap water safe for you to drink it wasn't loaded with bad bacteria. If warm water in the humidifier was sitting stagnant in the reservoir for days at a time it could harbor bacterial growth, but it doesn't sound like that was the problem. IMHO the problem with your jax is unique to him, and it could have been something lurking just under the surface for quite a while.
Just wondering if its possible its not actually a RI that is causing the symptoms. Possibilities could also include an irritation or injury to his esophagus or inside of his mouth, a stomach problem. Could you describe your nutritional supplementation and gutloading, both products used and schedule? How long have you had him? WC or CBB? What feeders do you use?
