Description

Helicobacter pylori strain 22317 is a Gram-negative bacterium characterized by its spirilla shape and microaerophilic oxygen requirement. It is distinguished by its single-cell arrangement and the presence of flagella, which contribute to its motility. This strain is mesophilic, with an optimal growth temperature of 37°C. H. pylori strain 22317 is associated with various hosts, including Homo sapiens (humans), Gallus gallus (chickens), Aves (birds), primates, and several mammalian and rodent species. Its biotic relationship is classified as free-living, indicating that it can survive independently within its host-associated habitats. The bacterium is known for its significant health effects, which include a wide range of gastrointestinal diseases. These effects encompass chronic gastric inflammation, gastric ulcers, and various forms of cancer, such as gastric carcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. Specifically, it is implicated in conditions like peptic ulcer disease, chronic gastritis, and dyspepsia, reflecting its role in both symptomatic and asymptomatic mucosal inflammatory responses. Interestingly, H. pylori strain 22317 highlights the complex interplay between microbial pathogens and host health, illustrating how a single bacterial strain can lead to diverse health outcomes in different host species. The strain's pathogenicity in humans underscores its relevance in clinical microbiology and public health, as it poses a risk for serious gastrointestinal diseases. Understanding its characteristics and effects can enhance our knowledge of its role in human health and disease.
