This paper devoted to the results of Helicobacter pylori infection spreading in Uzbekistan, its molecular-genetic characteristics, antibiotic resistance. It is shown that Uzbekistan belongs to the regions with a high degree of infection of the population of the HP. Pathogenic Cag positive bacterial strains were associated with chronic Helicobacter pylori associated gastritis. The resistance of HP to clarithromycin in the region was 13.3%.
