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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
