Helicobacter pylori strain 22211

Helicobacter pylori strain 22211 is a Gram-negative, microaerophilic bacterium with a spirilla shape and a single flagellum. This organism is host-associated, primarily colonizing the stomachs of various hosts, including Homo sapiens, Gallus gallus, and several other mammals and birds. It is notable for its free-living biotic relationship, suggesting it can survive in the gastrointestinal tract of its hosts. The optimal growth temperature for H. pylori strain 22211 is 37°C, placing it within the mesophilic temperature range. It possesses two membranes and a single replicon, characteristics typical of many bacteria. Its cellular arrangement is primarily in singles, indicating a solitary lifestyle rather than forming clusters or chains. H. pylori strain 22211 is associated with a range of significant health effects in its human hosts. These include chronic gastric inflammation, peptic ulcer disease, and various forms of gastric cancer, including adenocarcinoma and mucosa-associated lymphoid tissue lymphoma (MALT lymphoma). Additionally, it can contribute to conditions such as GERD and functional dyspepsia. The presence of this bacterium is often linked to an asymptomatic mucosal inflammatory response and can lead to more severe gastrointestinal diseases. The ecological role of H. pylori strain 22211 emphasizes its adaptability to host environments and its potential impact on human health, particularly in terms of gastrointestinal pathology. Understanding its pathogenicity can inform treatment strategies for the diseases associated with this organism.
