Description

Helicobacter pylori strain B712A is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and the presence of flagella. This strain is found in a host-associated habitat and exhibits a single-cell arrangement. It thrives optimally at 37°C, falling within a mesophilic temperature range, and is notable for its unique biotic relationship as a free-living organism. This strain has been linked to numerous health effects, primarily concerning the gastrointestinal system. It is associated with chronic gastric inflammation, gastritis, peptic ulcer disease, and various forms of gastric cancer, including adenocarcinoma and mucosa-associated lymphoid tissue lymphoma (MALT lymphoma). The pathogenicity of H. pylori B712A is particularly significant in humans, where it can lead to serious conditions such as gastric ulcers, GERD, and functional dyspepsia. H. pylori strain B712A has a single replicon and is enveloped by two membranes, which is typical for Gram-negative bacteria. Its diverse array of hosts includes Homo sapiens, various species of birds (Aves), rodents (Rodentia), and primates, indicating its ecological versatility. The presence of H. pylori in multiple host species suggests its potential role in interspecies transmission and ecological dynamics within microbial communities. The strain’s capacity to induce a range of gastrointestinal diseases highlights its importance in both clinical microbiology and public health.
