Description

Helicobacter pylori B38 is a Gram-negative, microaerophilic bacterium that belongs to the spirilla shape category and is characterized by its single-cell arrangement. This organism is notable for its pathogenicity, as it is associated with various gastrointestinal diseases, including peptic ulcers and gastric cancer. The bacterium is free-living, indicating that it can survive independently within its host-associated habitat. H. pylori B38 possesses flagella, which are essential for its motility, allowing it to navigate through the viscous environment of the stomach. It is nonsporulating and has a mesophilic temperature range, with an optimal growth temperature of 37°C. The bacterium contains a single replicon and is surrounded by two membranes, a feature consistent with its classification as a Gram-negative organism. The ecological role of H. pylori B38 can be significant, as it is often found in the human stomach, where it can influence the microbiome and affect host health. Its pathogenic nature and specific adaptations for survival in a microaerophilic environment underscore its ability to thrive in a niche that is hostile to many other microbial species. Understanding the traits of H. pylori B38 can provide insights into its interactions with the host and its implications for human health, particularly in relation to gastric diseases. The strain is cataloged under the accession number NC_012973.1, which may facilitate further research into its genetic and functional characteristics.
