Helicobacter pylori strain 22341

Helicobacter pylori strain 22341 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spiral (spirilla) shape. This strain is found in a host-associated habitat, primarily inhabiting the gastrointestinal tracts of various hosts, including Homo sapiens, Gallus gallus, Aves, Primates, Mammalia, Amoeba, Rodentia, Cricetinae, and Thais. It possesses a single replicon and is surrounded by two membranes, typical of Gram-negative bacteria. Strain 22341 is non-motile but has flagella, which may contribute to its ability to colonize the gastric mucosa. It thrives optimally at 37°C, within a mesophilic temperature range. The bacterium has been implicated in a variety of health effects, including chronic gastric inflammation, gastric ulcers, and various forms of gastric cancer, such as gastric carcinoma and mucosa-associated lymphoid tissue lymphoma. Additionally, it is associated with gastroesophageal reflux disease (GERD), peptic ulcer disease, and functional dyspepsia, among other gastrointestinal diseases. The pathogenicity of Helicobacter pylori strain 22341 in humans highlights its role in chronic gastric conditions and potential carcinogenic effects, making it a significant organism in medical microbiology. The ecological insight gained from studying this strain underscores the complex interactions between host and pathogen, emphasizing the importance of understanding H. pylori's role in gastrointestinal health and disease. Its presence can lead to a range of symptomatic and asymptomatic conditions, indicating its adaptability and impact on human health.
