Helicobacter pylori strain 38185

Helicobacter pylori strain 38185 is a Gram-negative, microaerophilic bacterium characterized by its spiral shape and presence of flagella. It is typically found in a host-associated habitat, primarily within the gastrointestinal tract of various hosts, including Homo sapiens (humans), Gallus gallus (chickens), and several other mammals and primates. The bacterium exhibits a single cell arrangement and is non-motile, despite having flagella, which contributes to its ability to navigate the mucosal surface of the stomach. H. pylori strain 38185 thrives optimally at 37°C, fitting within the mesophilic temperature range. It possesses two membranes and a single replicon, indicative of its cellular structure and genetic organization. Although it has free-living characteristics, its primary biotic relationship is with its hosts, where it can lead to significant health complications. This strain is notably pathogenic to humans, being associated with a range of gastrointestinal diseases, including chronic gastric inflammation, peptic ulcer disease, and various forms of gastric cancer, such as gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The presence of H. pylori can also lead to conditions like atrophic gastritis and dyspepsia, and it is implicated in the development of hypochlorhydria and functional dyspepsia. From an ecological perspective, the widespread presence of H. pylori across diverse hosts suggests a complex interplay between the bacterium and the host's immune responses, influencing gastric health and disease across species. Its ability to induce chronic inflammation and promote cancer underscores the significance of understanding its biology for public health and disease management.
