It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov.:297-405).NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021

Bacteria that cause stomach inflammation (gastritis) and ulcers in the stomach. This bacteria is the most common cause of ulcers worldwide. It is often referred to as H. pylori. H. pylori infection is usually acquired from contaminated food and water and through person to person spread. The infection is common in crowded living conditions with poor sanitation. In countries with poor sanitation, 90% of the adult population can be infected. In the U.S., 30% of the adult population is infected. One out of six patients with H. pylori infection develops ulcers of the duodenum or the stomach. This bacteria is also believed to be associated with stomach cancer and a rare type of lymph gland tumor called gastric MALT lymphoma. Infected persons usually carry the infection indefinitely, unless treated with medications to eradicate the bacteria. (MedicineNet.com)NCI ThesaurusU.S. National Cancer Institute, 2021
