Trouble with hognose RI not responding to antibiotics

[SeaPancake]

I'm not sure if there's any imaging that might be done that would have a chance of visualizing any foreign bodies (or growths?), but that's something you could run by the vet to see if they think it might be fruitful.

I'd personally do a PCR for viruses. Ferlavirus is a possible suspect, and serpentovirus does infect colubrids -- rarely, so far as we know currently, but research on this viral group is very new.

I'll definitely bring a PCR test up to the vet at his next appointment since he's only been tested for bacterial stuff, and I'll also ask if there's reasonable suspicion in terms of some sort of issue that a scan could detect. Thanks!
