Helicobacter pylori strain APR133

Helicobacter pylori strain APR133 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and presence of flagella. It typically exists as single cells and is optimized for a mesophilic environment, with an optimal growth temperature of 37°C. The strain is notable for being host-associated and demonstrates a free-living biotic relationship. It has a single replicon and is composed of two membranes. This strain has been identified in various hosts, including Homo sapiens, Gallus gallus, and other mammals and birds. Its pathogenicity in humans is significant, as it is associated with a range of serious health issues. These include chronic gastric inflammation, gastric ulcers, and more severe conditions such as gastric cancer, gastrointestinal diseases, and mucosa-associated lymphoid tissue (MALT) lymphoma. The presence of H. pylori is linked to various forms of dyspepsia and ulcers, including peptic and duodenal ulcers, and it can lead to atrophic gastritis and intestinal metaplasia. The ecological role of H. pylori strain APR133 highlights its adaptability to the human stomach, where it can survive and thrive while contributing to various gastrointestinal diseases. Its ability to induce chronic inflammation and potential carcinogenic effects underscores its significance in microbiological and medical research, particularly regarding gastric health and disease prevention.
