GENETIC DIVERSITY OF THE MYCOBACTERIUM TUBERCULOSIS ISOLATES IN THE REPUBLIC SAKHA (YAKUTIA), RUSSIA.

The population structure of the M. tuberculosis in Yakutia was estimated by the MIRU-VNTR method of 24 loci genotyping. 199 strains from 199 patients with pulmonary tuberculosis were tested.

Primary multidrug-resistant Mycobacterium tuberculosis in 2 regions, Eastern Siberia, Russian Federation.

Of 235 Mycobacterium tuberculosis isolates from patients who had not received tuberculosis treatment in the Irkutsk oblast and the Sakha Republic (Yakutia), eastern Siberia, 61 (26%) were multidrug resistant. A novel strain, S 256, clustered among these isolates and carried eis-related kanamycin resistance, indicating a need for locally informed diagnosis and treatment strategies.
