Campylobacter infection in humans.

Abstract

Campylobacter jejuni and Campylobacter coli are now recognized as common bacterial cause of enteritis in humans. They infect the healthiest of persons resulting in a self-limiting diarrhoea often accompanied by mucus and blood in the stool. On the other hand C. fetus subsp fetus attacks otherwise debilitated persons whose body defences have been weakened by underlying conditions, and causes extragastrointestinal campylobacteriosis. C. pylori, which is able to survive in the stomach acid environment, is now widely considered to be associated with gastritis, peptic ulcer, duodenal ulcer and non-duodenal ulcer, although its aetiologic role in the causation of the disease has not yet been established.
