Description

Helicobacter pylori strain SV397_2 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and presence of flagella, which enables motility despite a non-motile classification. This strain is typically found in a host-associated habitat and exhibits a cell arrangement of singles. It thrives optimally at a temperature of 37°C, categorizing it as mesophilic, and possesses a unique structure with two membranes and a single replicon. This strain is associated with a variety of hosts, including Homo sapiens (humans), Gallus gallus (domestic chickens), various Aves (birds), primates, mammals, and rodents, as well as amoebas. The pathogenicity of Helicobacter pylori strain SV397_2 is particularly significant in humans, as it is linked to numerous gastrointestinal diseases. Notable health effects include chronic gastric inflammation, gastric ulcers, and various forms of cancer, such as gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The extensive list of health issues associated with this strain underscores its potential impact on human health, particularly concerning chronic conditions like gastritis and peptic ulcer disease. Given its free-living biotic relationship and the diverse range of hosts it can inhabit, Helicobacter pylori strain SV397_2 serves as a critical example of a pathogen that not only affects its primary host but also has the capacity to influence the health of various species within its ecological niche. This highlights the importance of understanding host-pathogen interactions within microbiology and public health contexts.
