Study the prevalence and mechanisms of resistance in circulating C. diphtheriae strains. Materials and methods. 664 C. diphtheriae strains isolated in 1987 - 2013 in various regions of Russia and sent to the reference center of Gabrichevsky Moscow Research Institute of Epidemiology and Microbiology were the object of the study. Antibiotic sensitivity of the strains was studied by disk-diffusion and E-test methods using 10 antimicrobial preparations. Nucleotide sequence analysis was carried out by using BLAST program and EMBL/GenBank database. Results. Most of the studied strains turned out to be sensitive to all the antibacterial preparations used. 1.2% of C. diphtheriae strains turned out to be resistant to penicillin and 6.0% had intermediate level of resistance. 0.4 - 0.6% of the strains had intermediate level of resistance to macrolides, and 4.0 - 4.4% were resistant. 2.0% of the strains had multiple resistance. Erm(X)-specific PCR carried out in this study showed that all the C. diphtheriae strains resistant to macrolide antibiotics carry erm(X) gene. Conclusion. The results of the study indicate a fairly high level of prevalence for C. diphtheriae strains resistant to antibiotics.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Изучение распространенности и механизмов резистентности у циркулирующих штаммов C.diphtheriae. Материалы и методы. Объектом исследования явились 664 штамма C.diphtheriae, выделенные в 1987 - 2013 гг. в различных регионах России и присланные в референс-центр МНИИЭМ им. Г.Н.Габрического. Изучение антибиотикочувствительности штаммов осуществляли дискодиффузионным и E-test методами с использованием 10 антимикробных препаратов. Анализ нуклеотидных последовательностей проводили с использованием программ BLAST и базы данных EMBL/GenBank. Результаты. Большинство изученных штаммов оказались чувствительными ко всем используемым антибактериальным препаратам. Установлено, что 1,2% штаммов C.diphtheriae оказались резистентными к пенициллину и 6,0% имели промежуточный уровень устойчивости. Промежуточный уровень устойчивости к макролидам имели 0,4 - 0,6% штаммов, а резистентными оказались 4,0 - 4,4%. Множественной резистентностью обладали 2,0% штаммов. Проведенная в настоящем исследовании erm(Х)-специфическая ПЦР показала, что все резистентные к макролид-ным антибиотикам штаммы C.diphtheriae несут ген erm^). Заключение. Результаты исследований указывают на достаточно высокий уровень распространенности штаммов C.diphtheriae, устойчивых к антибиотикам.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Corynebacterium diphtheriae</kwd><kwd>Corynebacterium diphtheriae</kwd><kwd>antibiotics</kwd><kwd>resistance</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>антибиотики</kwd><kwd>резистентность</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Комбарова С.Ю., Мельников В.Г., Борисова О.Ю. и др.
