Abstract
Aim. Characteristics of contemporary strains of N. gonorrhoeae using NG-MAST genotyping (.Neisseria gonorrhoeae multi-antigen sequence typing), isolation of dominating variants and analysis of their territorial distribution. Materials and methods. 440 strains of N. gonorrhoeae isolated in 2012 - 2015 in 19 subjects of the Russian Federation were used in the study. Genotyping was carried out based on sequencing of variable regions of porB and tbpB genes. Identification of alleles and sequence-types was carried out according to http://www.ng-mast.net. Results. 172 NG-MAST genotypes were identified, 100 of which -were described for the first time. 807,1152, 1544,5714 and 5941 were predominating sequence-types, typical for several subjects of the Russian Federation and some neighboring countries, as well as sequence-types 8583 and 9476 described for the first time, that were exclusively distributed in the regions of their emergence. Sequence-types 225, 1407 and 2992, that are epidemically significant in distant countries, were represented by single isolates in this study. Conclusion. A peculiar and significant genetic diversity of N. gonorrhoeae strains, circulating in the Russian Federation, with characteristic bond of several NG-MAST genotypes to one or several regions, was shown.
