I recently went to check on a friends snakes while he was on vacation. They were freezing cold, burm had RI, Mouth rot and infection all over the belly. Boa wasn't as bad but both were taken to the vet and even with excellent vet care (herp specialist) the burm died. Boa is doing O.K. With that said, take it to the vet ASAP, find a herp specialist and get it looked at. DO NOT let it near any other reptiles you have. I'd even increase the quarantine time on this one. Good Luck.
