Abstract:
Despite the presence of studies devoted to the study of the bacterium Helicobacter pylori, its
role in the pathogenesis of diseases such as chronic gastritis, gastric and duodenal ulcers,
MALT lymphoma and gastric adenocarcinoma, the question of what determines the
development of one or another clinical form of gastroduodenal pathology remains open. One
of the factors with which the characteristics of clinical forms of Helicobacter pylori-associated
diseases are usually associated is the genetic characteristics of the microorganism, which
determines its virulence
