Helicobacter pylori strain B464A

Helicobacter pylori strain B464A is a microaerophilic, Gram-negative bacterium characterized by its spiral shape and presence of flagella. This strain is predominantly found in association with hosts, including Homo sapiens, Gallus gallus, and various other mammals and birds. It exists as single cells and has a mesophilic temperature range, with an optimal growth temperature of 37°C. The pathogenicity of H. pylori B464A is significant, as it is linked to various serious health conditions, including chronic gastric inflammation, gastric ulcers, and several forms of gastric cancer, such as adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. In addition to these serious health implications, the bacterium can also lead to functional dyspepsia and other gastrointestinal diseases. H. pylori B464A's biotic relationships are primarily free-living, allowing it to thrive in the gastric environment of its hosts. The bacterium's ability to adapt and survive in the acidic conditions of the stomach contributes to its role in gastrointestinal pathologies. Its pathogenic effects underscore the importance of understanding H. pylori in the context of human health and disease, particularly regarding its association with gastric cancer and other serious gastrointestinal disorders. The presence of this strain in a variety of hosts indicates a broader ecological significance, suggesting that H. pylori may play a role in the microbial dynamics of gastric environments across different species.
