GENETIC POLYMORPHISM OF MYCOBACTERIUM TUBERCULOSIS IN PATIENTS WITH TUBERCULOSIS AND HUMAN IMMUNODEFICIENCY VIRUS INFECTION IN EASTEN SIBERIA

A total 61 randomly selected strains of M. tuberculosis were genotyped by the 12 loci of MIRU-VNTR. It was shown the predominance of the Beijing genetic group (78,4 %) in population of mycobacterium from the patients with tuberculosis and. human immunodeficiency virus infection in Irkutsk region and. Buryatia. Multidrug resistance was observed in 34,4 % of the studied strains without significant differences among representatives of Beijing and non-Beijing

COMPREHENSIVE EPIDEMIOLOGICAL ANALYSIS OF THE TUBERCULOSIS SITUATION AMONG THE DIFFERENT ETHNIC GROUPS OF THE BURYATIA

Comprehensive epidemiological analysis of tuberculosis in the Republic of Buryatia (RB), including among different ethnicgroups (Russian, Buryat, Evenk) presents in the article. Assessment of the epidemiological situationfor 1994-2012 was examined on various parameters (incidence, prevalence and mortality). It was found that the epidemiological situation in RB in the last twenty years were characterized by high incidence of tuberculosis when compared with similar data for Russia as a whole (mean annual incidence 148,1 ± 6,90/0000 и 77.6 ± 2,10/0000 respectively). Among the various ethnic groups living in the RB, the most unfavorable epidemiological indicators identified for the Buryat population. "Safely" group of the population was Evenki. For each of the studied ethnic groups have been identified areas of tuberculosis risk, which had its own characteristics

INVESTIGATION PHYLOGENETIC RELATIONSHIPS MAJOR GENOTYPES MYCOBACTERIUM TUBERCULOSIS BY MIRU-VNTR-24 GENOTYPING

Thirty-one isolates of M. tuberculosis was identified in Buryatia by MIRU-VNTR-24 typing and deletion analysis by RD105 and RD207. Beijing family strains accountedfor 67,4 % and had a variety of profiles with a prevalence (22,6 %) of two modern epidemic subtype Beijing MIT17 and MIT16. Strains Beijing MIT 642 differed in the number of repeats of the variable loci, it may reflect a longer circulation of these subtypes without shaping their properties of epidemic circulating strains in modern populations, or they had epidemic importance in the past. It is also apparent heterogeneity in the number of loci among strains according to group LAM, T, and X, which requires additional research. The aim of this work was to determine the current epidemiologically important genotypes of Mycobacterium tuberculosis, as well as the genotypes had an epidemic importance in the past as an example of the region with a high prevalence of tuberculosis - the Republic of Buryatia
