This is a fascinating topic... And mildly disturbing as I have both boas, BPs, and others in my small mixed collection. All of mine did the typical quarantine period without any issues and are housed together. At this point, if any of mine happen to have IBD, I guess it's safe to assume that all of them have been exposed.

Running Elk- Maybe a cleaner like F10SC or F10SCXD would work to clean the rack with? I believe those cleaners are supposed to kill viruses, bacteria, and fungi, so I assume they would work on a virus like IBD (but have never used them to treat such). A bleach / water solution wouldn't hurt either.

Skiploder- Are you still adding animals to your collection at this point, and if so, do you have them tested for IBD before introducing them to your collection? Do you have your vet take blood samples and then send off to a lab or what is the procedure you use? Also, do you mind me asking how much you typically pay for testing to be done?

Unfortunately, there are no reptile-experienced vets in my area... I'm not even sure I'd feel confident in letting someone take a blood sample from one of my snakes, much less a biopsy... I'll have to consider this.
