| helicobacter pylori | A bacterium that has been implicated in the development of duodenal and gastric ulcers. Many gastroenterologists now advocate treating with antibiotic regimens to eradicate this microorganism in the upper gastrointestinal tract of those who suffer from recurrent or intractable peptic ulcer disease. Combinations of bismuth, metronidazole and ampicillin (or tetracycline) have been used successfully. Others advocate the use of omeprazole in combination with amoxicillin (or clarithromycin).
