Description

Helicobacter pylori OK310 is a microaerophilic, Gram-negative bacterium characterized by its spirilla shape and presence of flagella. This organism typically resides in host-associated habitats, specifically within the gastric mucosa of humans and other mammals. It is noteworthy for its single-cell arrangement and does not exhibit mobility, despite having flagella. H. pylori OK310 thrives optimally at 37°C, falling within the mesophilic temperature range. The bacterium possesses two replicons and is distinguished by having two membranes. Its biotic relationship is classified as free-living, indicating that, while it is commonly found in association with hosts, it may also exist independently under certain conditions. Understanding the characteristics of H. pylori OK310 is crucial, particularly given its role in human health, including its association with gastric disorders. The microaerophilic nature of this bacterium suggests that it requires specific oxygen levels for optimal growth, which aligns with its habitat within the stomach, where oxygen is limited. The presence of two membranes may provide additional protective mechanisms against the acidic environment of the gastric lumen. Overall, H. pylori OK310 serves as an important model for studying host-microbe interactions and the ecological dynamics within the gastric microbiome, highlighting the complex relationships that exist between pathogenic bacteria and their human hosts.
