Prevalence of IBD?

[Skiploder]

Before the blood test became available recently people used to pick up a normal male BP and house it in the same room/rack with their quarantined boa to act as a "canary in the coal mine". If the BP got sick then they knew the boa was a carrier. Crude, but cheap and effective. Not something I would do though, I'd just pay for the blood test if I were concerned.

...except that ball pythons don't die first, or faster or are any less able to remain asymptomatic carriers.
