The vet recommends euthanasia as there still is a lot unknown about IBS and they are concerned about contagion. It is really rare in snakes this young (4 months) I guess, and we caught it pretty early, but there still isn't any treatment that I have been told.
I have been extraordinarily careful with quarantine. I am OCD, and so have been super careful to the point of paranoid. We actually were more concerned it might be crypto, which even bleach doesn't kill. Soaking in pyroxide for 20+ minutes is recommended to kill crypto, so I have been Soaking the quarantine room in pyroxide (hopefully that would kill OBD virus as well),have a dedicated set of clothes for going in there, and wear surgical gloves. And now that I know I am still worried about my other little guy, but hope given my steps that transmission is unlikely. They are even on separate floors and at opposite ends of the house.
I am just incredibly bummed about the whole situation, as the last thing I want to do is euthanize the little guy. (Insert strong curse word here)
