Helicobacter pylori strain UM087

Helicobacter pylori strain UM087 is a Gram-negative bacterium characterized by its spiral shape and microaerophilic oxygen requirement. It is primarily found in host-associated environments, indicating its close relationship with various hosts, including Homo sapiens, Gallus gallus, and several other mammalian and avian species. The organism features a single replicon and possesses two membranes, consistent with its classification as a member of the Proteobacteria phylum. UM087 is non-motile despite having flagella, suggesting it relies on other mechanisms for colonization within the gastrointestinal tract. The optimal temperature for its growth is 37°C, within a mesophilic temperature range, which aligns with the conditions of the human stomach. This strain is notably pathogenic to humans, associated with a range of significant health effects, including chronic gastric inflammation, gastric ulcers, and various forms of gastric cancer, such as adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The bacterium is also implicated in the development of conditions like gastroesophageal reflux disease (GERD) and functional dyspepsia. The diverse host range and the extensive list of associated diseases highlight the ecological role of H. pylori strain UM087 in gastrointestinal pathology. Its presence can lead to severe health consequences, emphasizing the importance of understanding its biological interactions and potential for causing chronic infections within human and animal populations.
