Helicobacter pylori strain MM2005-126

Helicobacter pylori strain MM2005-126 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and presence of flagella, which facilitates mobility despite being categorized as non-motile in practical terms. This strain is typically found in host-associated habitats, primarily colonizing various hosts including Homo sapiens, Gallus gallus, and several other mammals and birds. It is a mesophilic organism, with an optimal growth temperature of 37°C. The strain is notable for its pathogenicity in humans, being associated with a range of gastrointestinal diseases. These include chronic gastric inflammation, gastric ulcers, and more severe conditions such as gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. Other health effects linked to this strain include functional dyspepsia, atrophic gastritis, and various forms of peptic ulcers. Helicobacter pylori MM2005-126 has a single replicon and is encased by two membranes, characteristic of its Gram-negative classification. Its biotic relationship is described as free-living, indicating its ability to exist independently within host environments, although it primarily thrives in the gastric mucosa. The ecological insight from this strain's characteristics highlights the complex interactions between H. pylori and its hosts, particularly the potential for chronic infection leading to serious health outcomes. Understanding these dynamics can inform strategies for managing and treating gastrointestinal diseases associated with this bacterium.
