H.pylori is probably the most common cause of chronic bacterial infection of humans, present in almost half of the world population. The presence of the bacterium in the gastric mucosa is associated with chronic active gastritis and is implicated in more severe gastric diseases, including chronic atrophic gastritis, peptic ulceration and mucosa-associated lymphoid tissue lymphomas. Strain J99 was isolated in the USA in 1994 from a patient with a duodenal ulcer."xsd:string |
