| [ Summary ] |
The types of bacteria which cause acute enteric infections include Campylobacter spp., Yersinia spp., Salmonella spp., Vibrio spp. and Clostridium difficile. Endoscopic findings of enteritis caused by these pathogens are commonly obtained by observation of the ileocecal region with colonoscopy. The basic findings are swelling of the ileocecal valve, as well as swelling, erosions and ulcers of lymphoid tissue in the terminal ileum. These findings are observed to various degrees according to the causative agents. Characteristic findings include ulceration of the ileocecal valve with Campylobacter enterocolitis and of the terminal ileitis with Yersinia infection. Recognition of these conditions is important because discrimination between these infectious diseases and non-infectious inflammatory bowel conditions may be problematic. Clostridium difficile enteritis, which rarely occurs after surgery for inflammatory bowel disease, should be kept in mind. |
