Материалы и методы. Изучены мутации генов у 247 штаммов М. tuberculosis, связанные с лекарственной устойчивостью к изониазиду, рифампицину, фторхинолонам и аминогликозидам. Генетическая устойчивость возбудителя туберкулеза определялась с помощью LPA (GenoType® MTBDRsl MTBDRplus и MTBDRsl, ver.2.0). Результаты исследования подтверждены определением фенотипической лекарственной устойчивости в автоматизированной системе BACTEC™ MGIT™ 960. Результаты. Определены штаммы лекарственно-устойчивых M. tuberculosis, циркулирующих на территории Гомельской области, микробиологическими методами подтверждена высокая достоверность определения молекулярно-генетической лекарственной устойчивости возбудителя туберкулеза (к изониазиду и рифампицину - в 97,2 %, к фторхинологам - в 85,1 %, к аминогликозидам - 92,3 % случаев). Выявлен значительный удельный вес штаммов лекарственно-устойчивых M. tuberculosis с мутациями генов (45,1 %), не включенных в систему GenoType® MTBDRsl. Заключение. Значительная генетическая вариабельность лекарственно-устойчивых штаммов M. tuberculosis требует комплексного использования всех методов определения устойчивости к лекарственным препаратам.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to determine the genetic and phenotypic drug resistance of M . tuberculosis to first-line and second-line anti-TB drugs. Material and methods. Gene mutations in 247 strains of M. tuberculosis (MBT) associated with drug resistance to isoniazid, rifampicin, fluoroquinolones, and aminoglycosides were studied. Genetic resistance of a tuberculosis causative agent was determined by means of LPA (GenoType® MTBDRsl MTBDRplus and MTBDRsl, ver.2.0). The results of the study are confirmed by the determination of phenotypic drug resistance in the automated system BACTEC ™ MGIT ™ 960. Results. The drug resistant MBT strains circulating around Gomel region have been determined, and the high reliability of molecular and genetic determination of MBT drug resistance has been confirmed by microbiological methods (isoniazid and rifampicin - 97.2 %, fluoroquinolones - 85.1 %, aminoglycosides - 92.3 %). A considerable number of drug resistant MTB strains with gene mutations (45.1 %) which are not included in the GenoType® MTBDRsl system were detected. Conclusion. Тhe considerable genetic variability of drug-resistant MBT strains requires complex application of all the methods of drug resistance testing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микобактерии туберкулеза</kwd><kwd>лекарственная устойчивость</kwd><kwd>мутации</kwd><kwd>молекулярно-генетические методы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mycobacterium tuberculosis</kwd><kwd>drug resistance</kwd><kwd>mutations</kwd><kwd>molecular and genetic methods</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">World Health Organization.
