[Regional ileitis - a diarrheal disease of pigs].

Morphological and histological changes were described in regional ileitis of pigs, which constitutes one of the forms of the complex of diseases referred to as intestinal adenomatosis of pigs. The most pronounced changes were concentrated on the ileum and were characterized, from the morphological point of view, by a distention of the intestinal wall and from the histological point of view, by proliferation of the epithelial cells of ileum, proliferation of the lymphatic tissue of tunica mucosae and submucosae, and hypertrophy of tunica muscularis. This disease has not been described in Czechoslovakia up to now.
