Helicobacter pylori strain GD63

Helicobacter pylori strain GD63 is a Gram-negative, microaerophilic bacterium known for its spiral shape (spirilla) and presence of flagella. This strain is characterized by a single-cell arrangement and is non-motile. It is mesophilic, with an optimal growth temperature of 37°C, and has two replicons and two membranes, which are typical features of bacteria in this genus. Strain GD63 is associated primarily with various hosts, including Homo sapiens (humans), Gallus gallus (chickens), Aves (birds), Primates, Mammalia, Amoeba, Rodentia, Cricetinae, and Thais. This wide range of hosts highlights its adaptability and potential for cross-species transmission. The health implications of H. pylori strain GD63 are significant, as it is linked to a variety of gastrointestinal diseases. These include chronic gastric inflammation, peptic ulcer disease, gastric ulcers, and various forms of gastric cancer, including adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. Additionally, it contributes to chronic gastritis and conditions like gastroesophageal reflux disease (GERD) and functional dyspepsia. The strain can induce an asymptomatic mucosal inflammatory response, leading to severe health consequences for affected individuals. The pathogenicity of H. pylori strain GD63 emphasizes its role in human health and disease, underlining the importance of understanding its biology and ecological relationships. Its presence in diverse hosts may contribute to the bacterium's persistence in various environments and its potential impact on gastrointestinal health across species.
