Helicobacter pylori strain ZH137 44

Helicobacter pylori strain ZH137 44 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spiral shape, classified as spirilla. It exists in a single-cell arrangement and possesses flagella, indicating motility, although it is noted as non-motile in behavior. This strain is mesophilic, with an optimal growth temperature of 37°C, which aligns well with the human body temperature, highlighting its adaptation to a host-associated habitat. ZH137 44 has a unique biotic relationship, being free-living yet primarily associated with various hosts, including Homo sapiens, Gallus gallus, and several other mammals and birds. Its pathogenicity is particularly significant in human health, as it is linked to a range of gastrointestinal diseases. These include chronic gastric inflammation, gastric ulcers, and various forms of gastric cancer, such as adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The strain is implicated in conditions like GERD, functional dyspepsia, and atrophic gastritis, signaling its role in serious health complications. The presence of a single replicon and two membranes suggests a simple yet effective genomic organization that may contribute to its adaptability in host environments. The extensive range of health effects associated with H. pylori ZH137 44 underscores its ecological impact on human health and suggests a complex interplay between the bacterium and its host, reinforcing the importance of studying such strains for understanding their role in gastrointestinal diseases.
