 In Campylobacter enterocolitis, lesions in the terminal ileum are relatively infrequent, and mainly occur in the large intestine. On the other hand, lesions are found in the terminal ileum in 80%of cases of Salmonella enterocolitis. These lesions are classified by site, i. e., whether they occur mainly in the ileocecum or the large intestine. Campylobacter enterocolitis and Salmonella enterocolitis are usually diagnosable by endoscopic examination of the large intestine. The lesions of Vibrio parahaemolyticus enterocolitis are mainly found in the small intestine, though the terminal ileum and ileocecal valve exhibit erosions and erythema. Yersinia enterocolitis and Typhoid fever demonstrate lesions in Peyer patches and isolated lymph nodes, though lesions are also found in the ileocecal valve and ascending colon. Erosions and aphthoid ulcers are mainly observed in Yersinia enterocolitis, while ulcers are frequently noted in Typhoid fever. Not only endoscopy but also abdominal echography and abdominal CT are useful in the diagnosis of these diseases.
