Helicobacter pylori strain ZH76 50

Helicobacter pylori strain ZH76 50 is a microaerophilic, Gram-negative bacterium characterized by its spirilla shape and the presence of flagella. This strain is notable for its habitat, primarily associated with hosts including humans (Homo sapiens), birds (Gallus gallus, Aves), various primates, and rodents (Rodentia, Cricetinae), as well as amoebae. It is free-living and has a single replicon, which is indicative of its genetic structure. The optimal growth temperature for H. pylori ZH76 50 is 37°C, placing it within the mesophilic temperature range. The pathogenicity of this strain is significant, as it is implicated in various gastrointestinal diseases and conditions. It is associated with chronic gastric inflammation, gastric ulcers, and more severe outcomes like gastric cancer, including adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. Other health effects include GERD, functional dyspepsia, and complications such as atrophic gastritis and intestinal metaplasia. The presence of this bacterium in human hosts suggests a complex biotic relationship that may lead to chronic health issues, particularly in the gastrointestinal tract. Understanding the ecological and biological interactions of H. pylori ZH76 50 with its hosts may provide insights into its role in gastric diseases, highlighting the importance of monitoring this strain in the context of public health.
