Description

Helicobacter pylori strain Hp H-44 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spirilla shape. It is typically found in a host-associated habitat, making it a significant organism in the study of human gastrointestinal health. The bacterium is motile, possessing flagella, which aids its movement within the stomach's acidic environment. Hp H-44 has a single replicon and is notable for its double membrane structure, a characteristic feature of Gram-negative bacteria. The optimal growth temperature for this strain is 37°C, placing it within the mesophilic temperature range, which is conducive to its survival in the human body. The organism exists as singles rather than in clusters or chains, reflecting its solitary lifestyle within the host. As a free-living organism, Helicobacter pylori Hp H-44 plays a pivotal role in the microbial community of the gastrointestinal tract. Its presence is often associated with various gastrointestinal diseases, including gastritis and peptic ulcers. Understanding its biological traits can provide insights into its ecological role and interactions within the host. The strain's adaptability to the microaerophilic environment of the stomach and its ability to thrive at body temperature highlight its specialization in colonizing the human gastrointestinal system. This specialization underscores the intricate relationship between host and microorganism, emphasizing the importance of H. pylori in human health and disease. Accessions for this strain include AKOP00000000.1, which can be referenced for further genetic and functional study.
