Helicobacter pylori strain 22367

Helicobacter pylori strain 22367 is a Gram-negative microaerophilic bacterium characterized by its spirilla shape and presence of flagella, which allows it to thrive in host-associated environments. This strain exhibits a single-cell arrangement and is classified as mesophilic, with an optimal growth temperature of 37°C. H. pylori strain 22367 is notable for its pathogenicity in humans and various hosts, including Gallus gallus (chickens), Aves (birds), Primates, Mammalia, Amoeba, Rodentia, and Cricetinae (hamsters). This bacterium is known to cause a range of gastrointestinal diseases, including chronic gastric inflammation, peptic ulcer disease, and various forms of gastric cancer such as adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. Additionally, it can lead to conditions such as GERD, functional dyspepsia, and atrophic gastritis. The strain's biotic relationship is described as free-living, indicating that it can exist independently while still having significant interactions with its hosts. The presence of two membranes suggests a complex cellular structure typical of Gram-negative bacteria, which may contribute to its pathogenic capabilities. In summary, Helicobacter pylori strain 22367 is a significant microbial agent in human health, being associated with various gastrointestinal diseases. Its adaptation to host environments and the ability to induce chronic inflammatory responses underscore its ecological role in disease dynamics within human populations and other associated hosts.
