Helicobacter pylori is a gram-negative, spiral-shaped bacteria that is found in half the world's population. In the United States, estimates suggest about 35% of the population is infected. H pylori infection is believed to occur most commonly through the oral-to-oral or fecal-to-oral route. A chronic inflammatory response occurs to some degree in all individuals who are infected with H pylori, although most infected individuals remain asymptomatic, with only minimal inflammation. Nevertheless, more serious outcomes do occur in a substantial proportion of patients, including peptic ulcer disease, gastric lymphoma, and gastric cancer.
