Helicobacter pylori strain 22346

Helicobacter pylori strain 22346 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spiral shape (spirilla). It is notable for its presence in a diverse range of hosts, including Homo sapiens, various bird species (Gallus gallus and Aves), Primates, Mammalia, Rodentia, Cricetinae, and even Amoeba, indicating a broad ecological adaptability. This strain typically exists in singles and possesses flagella, which may contribute to its motility in viscous environments, though it is described as non-motile. The optimal growth temperature for H. pylori strain 22346 is 37°C, placing it in the mesophilic range, which aligns with its association with warm-blooded hosts. The bacterium has one replicon and two membranes, typical of Gram-negative organisms. Its biotic relationship is categorized as free-living, which underlines its capability to survive in the gastrointestinal tracts of various organisms. Clinically, H. pylori strain 22346 is associated with a multitude of gastrointestinal diseases, including chronic gastric inflammation, gastric ulcers, and various forms of cancer such as gastric carcinoma and adenocarcinoma. It is also linked to conditions such as GERD and dyspepsia. The pathogenicity of this strain in humans is well-documented, underscoring its role in significant health issues. The diverse host range and significant health impacts of H. pylori strain 22346 highlight its ecological importance and the need for ongoing research to understand its interactions within different gastrointestinal environments and its implications for human health.
