Common Expressions: HELICOBACTER PYLORI

ExpressionsDefinition
Helicobacter pyloriHelicobacter pylori is a bacterium that infects the mucus lining of the human stomach. Many peptic ulcers and some types of gastritis are caused by H. pylori infection, although most humans who are infected will never develop symptoms. This bacterium lives in the human stomach exclusively and is the only known organism that can thrive in that highly acidic environment. It is helix-shaped (hence the name helicobacter) and can literally screw itself into the stomach lining to colonize. (references)

Specialty Expressions: HELICOBACTER PYLORI

ExpressionsDomainDefinition
Helicobacter pyloriGeologyH. pylori is a spiral-shaped pathogenic bacterium that infects the protective mucus that lines the stomach. Though some people suffer no ill effects, initial infections typically cause chronic gastritis and can lead to peptic ulcers or possibly stomach cancer (gastric adenocarcinoma). Many scientists believe that H. pylori is responsible for all non-medication-related cases of stomach ulceration, and the World Health Organization (WHO) has declared the microbe a Class 1 carcinogen. The infection can be cured and pre-cancerous tumors reversed with antibiotic treatment. (references)
Helicobacter pyloriHealthA spiral bacterium active as a human gastric pathogen. 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. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405). (references)
