Description

Helicobacter pylori strain VCT187-B122 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and the presence of flagella. This strain is adapted to a host-associated habitat, primarily infecting Homo sapiens, but it is also found in various other hosts, including Gallus gallus, Aves, Primates, Mammalia, Amoeba, Rodentia, and Cricetinae. VCT187-B122 exhibits a single cell arrangement and has a mesophilic temperature range, with an optimal growth temperature of 37°C. This strain is notable for its pathogenicity in humans, where it is linked to numerous gastrointestinal health issues. It is associated with conditions such as chronic gastric inflammation, gastric ulcers, and various forms of gastric cancer, including gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. Additionally, it can cause peptic ulcer disease and functional dyspepsia. The bacterium's ability to elicit an asymptomatic mucosal inflammatory response further complicates its role in gastrointestinal disease. The presence of two membranes and a single replicon suggests a complex cellular structure that may contribute to its survival and pathogenic mechanisms within the gastric environment. The diverse range of hosts indicates its ecological versatility and potential evolutionary adaptations, allowing it to exploit different biological niches. Overall, Helicobacter pylori strain VCT187-B122 exemplifies the intricate relationship between microbial pathogens and their hosts, highlighting the significant health impacts of this bacterium in human populations and its potential effects on broader ecosystems through its interactions with a variety of hosts.
