Abstract
A total of 397 strains of Mycobacterium tuberculosis isolated from newly diagnosed patients with pulmonary tuberculosis in the Omsk oblast in 2019–2020 were genotyped. The prevalence of the Beijing genotype strains (70.8%), in particular, of two modern sublineage clusters: Central Asian/Russian (46.1%) and B0/W148 (19.1%), was established. Strains of the ancient sublineage of the Beijing genotype were represented by clusters 1071-32 and 14717-15, totaling 4.8%. Compared with other genotypes, the strains of B0/W148-cluster and the ancient Beijing sublineage were more often characterized by multidrug resistance (MDR): 93.4 and 94.7%, respectively (P < 0.0001). Among members of other genetic families (LAM, Ural, T, Haarlem), drug-sensitive strains predominated (75.0%). The circulation of MDR Beijing strains requires molecular epidemiological surveillance in view of their possible wider spread.
