Helicobacter pylori str. ZH118

Helicobacter pylori strain ZH118 is a Gram-negative bacterium characterized by its spirilla shape and single-cell arrangement. This microbe is adapted to a microaerophilic environment, thriving in conditions with reduced oxygen levels, which is typical of its natural habitat associated with various hosts, particularly in the gastric environment of mammals. The optimal growth temperature for H. pylori str. ZH118 is approximately 37.0°C, aligning with the physiological temperature of many mammalian hosts. As a member of the Helicobacter genus, this strain exhibits the hallmark traits of its relatives, including the capability to survive in acidic conditions, which is an essential feature for colonization of the stomach lining. The adaptation to a host-associated habitat suggests a complex interplay with the host's immune responses and gastric microbiota, which may influence the strain's survival strategies and potential roles in the gastric ecosystem. Further studies on Helicobacter pylori str. ZH118 could provide valuable insights into its specific interactions with host factors, contributing to a broader understanding of the dynamics within the gastric microbiome and the evolutionary adaptations of microaerophilic organisms in host-associated environments.
