Gastric campylobacter-like organisms: their role in gastric disease of laboratory animals

Campylobacter pylori, first isolated in 1982, is now recognized as a primary cause of acute gastritis in man, and there is substantial data suggesting that this organism also plays an important role in the pathogenesis of duodenal ulcers. More recently, Campylobacter-like organisms and other morphologically distinct spiral bacteria have been isolated from gastric lesions in a variety of laboratory animal species. The zoonotic significance of C. pylori and other gastric spiral bacteria isolated from man as well as laboratory and domestic animals requires further study. An appreciation of the ecological and pathological role of gastric spiral bacteria in domestic and laboratory animals is an essential first step when considering the role and proper selection of animal models in the study of C. pylori gastroduodenal disease.
