Bingo!!! There is a lot of misconstrued info that flies around the internet and gets passed on as if it is gospel. Truth is, IBD is at best, a very poorly understood condition. There is very little known as to how long it can lie dormant in an animal, boa or python, or how long either a boa or python can actively carry symptoms before it kills them. I think the main reason that people are so attached to the idea that it kills pythons so swiftly, is that in the majority of earlier documented IBD cases, it was in pythons. Now the tide has turned a bit, and as of somewhat recent, it has been seen primarily in boas.
