Development of Staphylococcus haemolyticus strain typing method based on multilocus sequencing for resolving problems of molecular epidemiology. Materials and methods. 102 strains of coagulase negative staphylococci (CNS) isolated in hospitals of various specialization in N.Novgorod and Moscow were studied. Species identification of strain was performed by using tuf gene fragment sequencing, S.haemolyticus strain differentiation - by MLST results. eBURST approach was used for cluster analysis of MLST data; structural changes in tagatose-6-phosphate kinase were studied by using InterProScan platform and SWISS-MODEL site programs; MLST scheme gene allele variability analysis was performed by using MEGA 4.0 program package. Results. In the 102 strains sampled CNS was detected in 28 strains of the S.haemolyticus species. The MLST scheme developed for the first time for S.haemolyticus including mvaK, rphE, tphK, gtr, arcC, triA, aroE genes allowed the differentiation of the sampled strains by 11 genotypes. Strains with ST 3, 8, 6, 1, 4, 5 and 11 differed by highest epidemiologic significance. Cluster and phylogenetic analysis of the data obtained showed a high adaptive ability of the nosocomial S.haemolyticus strains. Multiresistance to antibacterial preparations was detected in the analyzed strains. Conclusion. The MLST method developed was effective in the differentiation of S.haemolyticus strains that circulate in hospitals and threaten both neonates and hospitalized adult patients.</p></abstract><trans-abstract xml:lang="ru"><p>Цель . Разработка метода типирования штаммов S.haemolyticus на основе мультилокусного секвенирования для решения задач молекулярной эпидемиологии. Материалы и методы. Изучали 102 штамма коагулазоотрицательных стафилококков (КОС), выделенных в стационарах различного профиля Н.Новгорода и Москвы. Видовую идентификацию штаммов проводили на основе секвенирования последовательностей фрагмента гена tuf, дифференциацию штаммов S.haemolyticus - по результатам MLST. Для кластерного анализа данных MLST использован подход eBURST; изучение структурных изменений в тагатозо-6-фосфат киназе проведено с помощью платформы InterProScan и программ сайта SWISS-MODEL; анализ изменчивости аллелей генов схемы MLST выполнен на основе пакета программ MEGA 4.0. Результаты. В выборке 102 штаммов КОС выявлено 28 штаммов вида S.haemolyticus. Разработанная впервые схема MLST для S. haemolyticus, включающая гены mvaK, rphE, tphK, gtr, arcC, tpiA, aroE, позволила дифференцировать выборку штаммов по 11 генотипам. Штаммы с ST 3, 8, 6, 1, 4, 5 и 11 отличались наибольшей эпидемиологической значимостью. Кластерный и филогенетический анализ полученных данных показал высокую адаптационную способность внутрибольничных штаммов S.haemolyticus. У проанализированных штаммов выявлена мультирезистентность к антибактериальным препаратам. Заключение. Разработанный метод MLST эффективен в дифференциации штаммов S.haemolyticus, циркулирующих в стационарах и представляющих опасность как для новорожденных, так и для госпитализированных взрослых пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>MLST</kwd><kwd>hemolytic staphylococci</kwd><kwd>MLST</kwd><kwd>multiresistance to antibiotics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гемолитические стафилококки</kwd><kwd>мультирезистентность к антибиотикам</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Акатов А.К., Зуева В.С.
