While the summary is interesting, there were a few questions left unanswered that IMO are important.
- How were the test subject selected?
- How old were the test subjects?
- How many times had each test subject been moved to a different collection?
- What kinds of collections and/or sellers are in each snake's history (e.g. private owners only vs large wholesaler vs pet store)?
- Were all of the test subjects from the same current collection?
- If the answer to the prior question is "No", how many of the snakes that tested positive but were asymptomatic were from a collection with one that tested positive and was showing symptoms of the disease?
- Had IBD ever been suspected in the collection(s) from which these snakes were drawn prior to the study?
