[Identification of ubiquitous and endemic Mycobacterium tuberculosis genotypes in the Republic of Buryatia].

The MIRU-12 and MIRU-24 methods were used for genotyping and estimation of M. tuberculosis population structure in Buryatia. It was studied in 283 strains isolated from individuals from the regional TB dispensary and medical clinics of the penitentiary system of the republic. It was found that the prevalence of pandemic genotypes Beijing MIT17 and MIT16 and also subtype Beijing MIT642 (24.5% - 46/188) in the studied area were dominant. The isolates of the Beijing MIT642 were common among all groups of patients with pulmonary tuberculosis with the tendency to formation of MDR and chronic course of the disease.
