Helicobacter pylori strain ATCC 43504

Helicobacter pylori strain ATCC 43504 is a Gram-negative bacterium that exhibits a spirilla shape and is characterized as microaerophilic, thriving optimally at 37°C within a mesophilic temperature range. This strain is notable for its presence in various hosts, including Homo sapiens, Gallus gallus (chickens), Aves (birds), Primates, Mammalia, Amoeba, Rodentia, and Cricetinae. It has a free-living biotic relationship and is equipped with flagella, though it does not exhibit mobility. H. pylori strain ATCC 43504 bears significant health implications, being associated with a range of gastrointestinal disorders. These include chronic gastric inflammation, peptic ulcer disease, and various forms of gastric cancer, such as gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The organism is also linked to conditions like GERD, functional dyspepsia, and atrophic gastritis, underscoring its pathogenicity in humans. Additionally, the bacterium contains three replicons and has a dual membrane structure. The presence of H. pylori in the human gastric mucosa can lead to asymptomatic mucosal inflammatory responses, but it is primarily recognized for its role in eliciting severe gastric conditions and cancers. This highlights the ecological significance of H. pylori in the human gut, where it not only adapts to the host environment but also plays a crucial role in the pathogenesis of gastrointestinal diseases. Such insights emphasize the importance of understanding H. pylori's biology and its impact on human health.
