Review of Research on Routes of Helicobacter pylori Infection

摘要

In recent years, many scholars conducted in-depth research on Helicobacter pylori and identified it as an important pathogen of chronic gastritis and peptic ulcer. H. pylori also causes also and contributes to precancerous lesions (atrophic gastritis and intestinal metaplasia) and is closely related to occurrence and development of gastric adenocarcinoma and gastric mucosa-associated lymphoma. This study summarizes biological characteristics, epidemic status, and infection route of H. pylori and reviews research on roles of natural environments, especially drinking water, during infection.
