Helicobacter pylori strain AFR58

Helicobacter pylori strain AFR58 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spiral-shaped morphology. This strain is primarily host-associated, with a notable presence in various hosts including Homo sapiens (humans), Gallus gallus (chickens), Aves (birds), various primates, Mammalia, and specific rodent species such as Cricetinae. The organism is non-motile despite having flagella, and it typically exists as single cells. Helicobacter pylori AFR58 is mesophilic, with an optimal growth temperature of 37°C, which aligns with the human body temperature, facilitating its pathogenic interactions within the gastrointestinal tract. The bacterium has a single replicon and is characterized by a double membrane structure, common to Gram-negative organisms. This strain is well-documented for its association with several 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 health effects attributed to H. pylori AFR58 underscore its significant role in chronic conditions, including gastritis, GERD, and dyspepsia, thereby impacting human health profoundly. From an ecological perspective, the presence of H. pylori across diverse hosts suggests a complex biotic relationship that may influence host health and disease outcomes. Its adaptability to different environments and hosts reflects the intricate nature of host-pathogen interactions in gastrointestinal microbiomes.
