Helicobacter pylori strain 1152/04

Helicobacter pylori strain 1152/04 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and single-cell arrangement. It possesses flagella, enabling motility, although the strain is reported as non-motile. This organism thrives in host-associated habitats, with an optimal growth temperature of 37°C, typical of mesophilic bacteria. It features a dual membrane structure and has one replicon. H. pylori strain 1152/04 is of significant concern in human health, being linked to chronic gastric inflammation, gastric ulcers, and various forms of gastric cancer, including adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. It is also associated with other gastrointestinal diseases such as GERD, dyspepsia, and peptic ulcer disease. The strain can provoke an asymptomatic mucosal inflammatory response, leading to conditions like atrophic gastritis and intestinal metaplasia. The bacterium has a broad range of potential hosts, including Homo sapiens, Gallus gallus (chickens), various Aves, Primates, Mammalia, Amoeba, Rodentia, and Cricetinae (such as hamsters). This diverse host range underscores the ecological versatility of H. pylori. Its ability to establish infections in different species, particularly humans, highlights its pathogenicity and adaptability. Understanding the ecological and biological interactions of H. pylori strain 1152/04 can provide insights into its role in human gastrointestinal disease and potential avenues for treatment and prevention.
