Helicobacter pylori strain ZH27 57

Helicobacter pylori strain ZH27 57 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and presence of flagella. It is typically found in a host-associated habitat, specifically within the digestive tracts of various hosts, including Homo sapiens, Gallus gallus, Aves, Primates, Mammalia, Amoeba, Rodentia, and Cricetinae. This strain exhibits a single cell arrangement and possesses two membranes, consistent with its classification as a Gram-negative organism. With an optimal growth temperature of 37°C, H. pylori strain ZH27 57 is classified as mesophilic, thriving within the temperature range suitable for many warm-blooded hosts. It has one replicon, indicating a streamlined genetic structure typical of many bacterial species. This strain is notably pathogenic to humans, linked to a range of gastrointestinal diseases, including chronic gastric inflammation, peptic ulcer disease, gastric cancer, and various forms of gastritis. The health effects associated with H. pylori infection encompass a spectrum from asymptomatic mucosal inflammatory responses to severe conditions like gastric adenocarcinoma and MALT lymphoma. The ecological role of H. pylori strain ZH27 57, while primarily free-living within its host, underscores the complex relationships bacteria can establish with their environments. Its pathogenicity highlights the significant impact that a single microbial strain can have on human health and disease, reinforcing the importance of understanding host-microbe interactions in gastrointestinal health.
