Description

Helicobacter pylori strain 22385 is a Gram-negative, microaerophilic bacterium characterized by its spiral shape (spirilla) and single-cell arrangement. It possesses flagella, which facilitate its mobility, although it is noted that it does not exhibit active movement. This strain is typically found in host-associated habitats, primarily infecting Homo sapiens and several other species, including Gallus gallus, various Aves, Primates, Mammalia, Amoeba, Rodentia, and Cricetinae. Strain 22385 thrives optimally at 37°C and falls within the mesophilic temperature range. It contains a single replicon and is encapsulated by a double membrane structure, characteristic of Gram-negative bacteria. Despite being classified as free-living, its biotic relationship primarily involves pathogenic interactions with its hosts. The health effects associated with H. pylori strain 22385 are significant, as it is linked to a variety of gastrointestinal diseases. These include chronic gastric inflammation, peptic ulcer disease, gastric cancer, and several other conditions such as gastritis, dyspepsia, and MALT lymphoma. The bacterium's ability to induce chronic mucosal inflammatory responses can lead to serious complications, including atrophic gastritis and dysplasia, ultimately contributing to the development of gastric carcinoma. Ecologically, the presence of H. pylori in various hosts suggests a complex interplay between the bacterium and its environment, highlighting its potential role in influencing gastrointestinal health and disease across multiple species. Understanding the pathogenicity and ecological relationships of strain 22385 may provide insights into broader microbial interactions and their impacts on host health.
