Выявлено 5 различных мутаций в кодоне 306 и 3 мутации – в кодоне 406 гена embB. Выявленные мутации подтверждены методами секвенирования и масс-спектрометрии. В результате анализа частоты встречаемости выявленных embB мутаций разработан набор реагентов для экспресс-определения лекарственной устойчивости микобактерий туберкулеза (МБТ) к этамбутолу методом мультиконкурентной аллель-специфичной ПЦР в реальном времени. Из 107 исследованных образцов клинических изолятов в 49 (45,8%) обнаружены мутации гена embB МБТ, в 58 (54,2%) – мутаций не обнаружено. В 39 (36,4%) образцах выявлены мутации в 306-м кодоне гена embB, в 9 (8,4%) – обнаружены мутации в 406-м кодоне, и 1 (0,9%) образец определен с мутациями и в 306-м, и в 406-м кодонах. Высокий уровень совпадения результатов молекулярно-генетического и бактериологического анализа лекарственной чувствительности/устойчивости (84%) показал высокую значимость мутаций в кодонах 306 и 406 гена embB МБТ и необходимость их обязательного определения для выявления этамбутол-устойчивых штаммов МБТ. При использовании молекулярно-генетического анализа установлен уровень чувствительности исследования 75,8% при специфичности относительно стандартных культуральных методов 95,6%.</p></abstract><trans-abstract xml:lang="en"><p>Based on real-time allele-specific polymerase chain reaction, the ranges of potential mutations in codons of 306 and 405 of the embBgene in Mycobacterium tuberculosis associated with resistance to ethambutol were investigated. 5 different mutations were detected in codon 306 and 3 mutations were found in codon 406 of the embB gene. The detected mutations were confirmed by sequencing and mass spectrometry. By analyzing the frequency of detected mutations of , the set of reagents was developed for rapid testing of susceptibility tuberculous mycobacteria to ethambutol by multi-competitive allele-specific real-time PCR. Out of 107 tested specimens of clinical isolates, mutations of the embB gene of M. tuberculosis were detected in 49 (45.8%) specimens, and no mutations were found in 58 (52.2%) specimens. 39 (36.4%) specimens had mutations in codon 306 of the embB gene, and 9 (8.4%) specimens had a mutation in codon 406, and 1 (0.9%) specimen had mutations in both codons 306 and 406. The high level of agreement in the results of molecular genetic and bacteriological tests (84%) proved the significance of mutations in codons 306 and 406 of the embB gene in M. tuberculosis and the need for their identification in order to detect ethambutol resistant strains of M. tuberculosis. When using molecular genetic tests, the sensitivity level made 75.8%, while the specificity of standard culture-based methods makes 95.6%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микобактерии туберкулеза</kwd><kwd>лекарственная устойчивость</kwd><kwd>этамбутол</kwd><kwd>аллель-специфичная ПЦР в реальном времени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tuberculous mycobacteria</kwd><kwd>drug resistance</kwd><kwd>ethambutol</kwd><kwd>real-time allele-specific PCR</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">Аляпкина Ю.
