To assess the prevalence of erythromycin and tetracycline-resistant S.mutans strains, isolated from child dental deposit; to determine the leading mechanism of their resistance to microlides. Materials and methods. Eighty six S. mutans strains, isolated from the dental deposits of children aged 6-17 years were studied. Screening of erythromycin resistance was fulfilled with two methods - phenotypical and genotypical, tetracycline - with phenotypical alone. Results. The share of S. mutans isolates, phenotypically resistant to erythromycin, was 16 % , to tetracycline - 26,7 %. The prevailing molecular-genetic mechanism of erythromycin resistance - presence of mef A-gene (78,6 % of all erythromycin-resistant strains); 10,5 % of all the studied S. mutans strains is a potential reservoir of antibiotic resistance genes ( erm B and mef A) in the horizontal transmission.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Оценить распространенность эритромицин- и тетрациклинрезистентных штаммов S. mutans , изолированных из зубного налета детей. Определить ведущий механизм их устойчивости к макролидам. Материалы и методы. Исследовано 86 штаммов S. mutans , изолированных из зубного налета детей в возрасте 6-17 лет. Скрининг на резистентность к эритромицину осуществлялся двумя методами - фенотипическим и генотипическим, к тетрациклину - только фенотипическим. Результаты. Доля изолятов S. mutans , фенотипически резистентных к эритромицину, составила более 16,0 %, к тетрациклину - 26,7 %. Преобладающий молекулярно-генетический механизм резистентности к эритромицину - наличие mef A-гена (78,6 % всех эритромицинрезистентных штаммов); 10,5 % всех исследованных штаммов S. mutans являются потенциальным резервуаром генов антибиотикорезистентности ( erm B и mef A) в горизонтальной передаче.</p></trans-abstract><kwd-group xml:lang="en"><kwd>S. mutans</kwd><kwd>Viridans Streptococci</kwd><kwd>erm B</kwd><kwd>mef A</kwd><kwd>S. mutans</kwd><kwd>Viridans Streptococci</kwd><kwd>antibiotic resistance genes</kwd><kwd>erm B and mef A</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гены антибиотикорезистентности</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bruckner L., Gigliotti F.
