The research done on this disease was fairly limited and conducted in the early 90's when the disease was first described at MIT. Because the most populous cell in the inflamed intestine in this variant is the eosinophil, which modulates allergies as well as fights parasitic infections. the assumption since that time was that the disease was either allergic or parasitic in nature. Parasites have never been identified in these cases, although most of us pathologists have spent many fruitless hours looking. The assumption that it is an allergic condition is extremely difficult to prove, due to the tremendous number of factors in the average ferret diet, and the fact that there is no readily available model or line of ferrets that will develop the condition with any reproducibility. EGE is a sporadic and as yet uncommon disease. Now anecdotally, these animals appear to do better on a turkey-based diet rather than chicken, and this has been shown in quite a few cases, but that is a long way from saying that this is a food allergy. Plus the disease itself is not similar at all to other inflammatory bowel diseases which have a known food trigger, such as sprue in humans.
