Abstract

The characteristic lesion of proliferative ileitis is segmental thickening of the small intestine (Jacoby 1978), particularly the distal ileum (Figs. 366, 367), but a similar lesion occasionally develops in the proximal colon. The lesion is usually well demarcated, and the transition from thickened to normal intestine is especially abrupt at the ileocecal junction. The cecum is often flaccid and filled with fetid liquid contents. Affected hamsters are usually dehydrated, and their perianal skin may be wet or matted with liquid feces, a sign for which the term “wet-tail” is commonly used.

Synonyms

Transmissible ileal hyperplasia hamster enteritis hamster ileitis regional ileitis terminal ileitis enzootic intestinal adenocarcinoma wet-tail
