Helicobacter pylori strain 207/99

Helicobacter pylori strain 207/99 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spirilla shape. This strain is notable for its presence in a diverse range of hosts, including Homo sapiens, Gallus gallus, various Aves, Primates, Mammalia, Amoeba, Rodentia, and Cricetinae. It exhibits a free-living biotic relationship and is typically found in the host-associated habitat. With a single replicon and two membranes, H. pylori strain 207/99 thrives optimally at 37°C within a mesophilic temperature range. While it possesses flagella, indicating potential mobility, it is noted that this strain does not demonstrate movement. The health implications of H. pylori strain 207/99 are significant, as it is associated with a multitude of gastrointestinal diseases and conditions, including chronic gastric inflammation, gastric cancer, gastric ulcers, and various forms of dyspepsia. The bacterium can lead to serious complications such as mucosa-associated lymphoid tissue (MALT) lymphoma and adenocarcinoma of the stomach, reflecting its pathogenic nature in human hosts. Given its extensive association with various gastrointestinal diseases, H. pylori strain 207/99 serves as a critical organism in understanding the links between bacterial infections and cancer development, particularly in the gastric environment. Its presence and pathogenicity underscore the importance of monitoring and addressing H. pylori infections to mitigate associated health risks.
