Helicobacter pylori strain UM202

Helicobacter pylori strain UM202 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spirilla shape. It is typically found in a host-associated habitat, primarily residing in the gastrointestinal tract of various hosts, including Homo sapiens and several other species such as Gallus gallus and Rodentia. This strain has a single replicon and two membranes, indicating its complexity as a prokaryotic organism. UM202 is non-motile, despite possessing flagella, and it thrives optimally at a temperature of 37°C, fitting within the mesophilic temperature range. The pathogenicity of H. pylori strain UM202 is significant, as it is associated with a range of gastrointestinal diseases. These include chronic gastric inflammation, gastric ulcers, gastritis, and various forms of gastric cancer, such as gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. The bacterium can lead to serious health conditions, including peptic ulcer disease and atrophic gastritis. The presence of H. pylori in the gastrointestinal tract can elicit an asymptomatic mucosal inflammatory response, but it is also linked to severe outcomes like stomach carcinoma and dyspepsia. Understanding the ecological role of H. pylori strain UM202 in its hosts is crucial, as it highlights the complex interactions between this bacterium and its human and animal hosts, emphasizing its potential impact on gastrointestinal health and disease.
