Spoligotyping revealed 28 spoligotypes; the greatest number of strains belonged to genetic families Beijing and LAM. The typing of 59 strains of spoligotype SIT1 (Beijing) allowed to differentiate 19 variants of IS6110-RFLP-profiles: 13 of them were individual and 6 were presented by clusters. The clusters А0 and В0 included the greatest number of M. tuberculosis strains — 21 (35,6%) and 17 (28,8%) accordingly. The high frequency of MLU and SLU of Beijing strains was associated with mutations rpoB Ser531→Leu and katG Ser315→Thr. The strains of M. tuberculosis belonged to another genetic families (T, H, Ural, U) have shown drug resistance more often. The level of resistance to isoniazid in vitro in MLU/SLU strains of MBT of different genotypes, especially, was high in case of mixed mutations such as katG Ser315→Thr и inhA_T15. The rates of viability and cytotoxicity of MBT strains of studied genotypes with different spectrum of mutations and phenotypic drug resistance were not substantially distinguished.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Резюме. </bold>Исследованы лекарственная чувствительность, спектр мутаций, обусловливающих резистентность к рифампицину и изониазиду, жизнеспособность, цитотоксичность и проведено генотипирование 111 клинических изолятов Mycobacterium tuberculosis (МБТ). Сполиготипирование выявило 28 сполиготипов; наибольшее число штаммов принадлежало к генетическим семействам Beijing и LAM. Типирование 59 штаммов сполиготипа SIT1 (Beijing) позволило дифференцировать 19 вариантов IS6110-RFLP-профилей: 13 были индивидуальны, 6 — представлены кластерами. Кластеры А0 и В0 включали наибольшее число штаммов M. tuberculosis — 21 (35,6%) и 17 (28,8%) соответственно. Высокая частота МЛУ и ШЛУ штаммов Beijing была ассоциирована с мутациями rpoB Ser531→Leu и katG Ser315→Thr. Штаммы M. tuberculosis других генетических семейств (T, H, Ural, U) чаще проявляли лекарственную чувствительность. Уровень устойчивости к изониазиду in vitro МЛУ/ШЛУ штаммов МБТ различных генотипов, особенно LAM, был высоким при сочетании мутаций katG Ser315→Thr и inhA_T15. Показатели жизнеспособности и цитотоксичности штаммов МБТ изученных генотипов с разнообразными спектрами мутаций и фенотипической лекарственной устойчивости существенно не различались.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Mycobacterium tuberculosis</kwd><kwd>genotype</kwd><kwd>drug resistance</kwd><kwd>mutations</kwd><kwd>viability</kwd><kwd>virulence</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Mycobacterium tuberculosis</kwd><kwd>генотипы</kwd><kwd>лекарственная устойчивость</kwd><kwd>мутации</kwd><kwd>жизнеспособность</kwd><kwd>вирулентность</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
