title: The spectrum of gastric disease associated with Helicobacter pylori and other infectious gastritides.
abstract: Helicobacter pylori is the most frequent infection of the stomach worldwide. Some of the people infected with H. pylori develop symptoms of dyspepsia that correlate with pathologic evidence of gastritis and peptic ulcers. In addition, H. pylori has been associated with preneoplastic lesions and with two neoplasias: intestinal-type gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. Rarely, gastric pathology can also be caused by other infectious agents, including fungi, other bacteria, parasites, and viruses. This review describes H. pylori-associated pathology and pathologies related to other infectious agents.
