MeSH Heading: Helicobacter pylori
Tree Number(s): B03.440.500.550; B03.660.150.235.500.250.550
Unique ID: D016480
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D016480
Annotation: infection: coordinate with HELICOBACTER INFECTIONS
Scope Note: A 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).
