IBD is often jumped on. There is lots of miss information and poor understanding of this disorder. Even when asked the foremost researchers answer with unknown and inconclusive far too often. Most of the research is being done on Boidae and not pythons. It is possible but there could be many other reasons too. Have you treated for mites at all in the near past? It could easily be poisoning.
As a completely sad note and I am very sorry for mentioning it but if it turns out to be IBD some thought might be given into contacting Dr. Jacobson
A partial correspondence I have had with him and his lab.
"Hi Alexander,
We are currently validating several diagnostic tests that can be used to screen IBD snakes with blood samples. We focused on boa constrictors, which seem to be the most common species that are infected during the pass 10 years. I believe that right now, we don't yet know the exact disease transmission and pathogenesis. So it is hard to conclude how a species response to IBD progression. Most of the assumptions were based on observation in very small sample size, which can be highly biased.
We currently accept blood and tissues samples for IBD testing, which is $100 each case. If you have confirmed IBD material of non-boa species, we may be interested in testing them for research collaboration.
