Along with the increasing access to orthopedic care, the number of patients with orthopedic infection, the etiological agents of which can be from various taxonomic groups, is also increasing. <italic>Staphylococcus aureus</italic> and different types of coagulase-negative staphylococci (CoNS), including <italic>S. epidermidis</italic> and <italic>S. lugdunensis</italic>, together are the causative agents in 70% of cases.</p> <p><bold>Aim of the study</bold> — to analyze the dynamics of the microbial spectrum isolated from patients of the septic surgery department for the period from 2011 to 2022.</p> <p><bold>Methods.<italic> </italic></bold>We performed a retrospective analysis of the microbial spectrum isolated from patients who were treated in the septic surgery department from January 1, 2011 to December 31, 2022. The leading pathogens were microorganisms whose share in the spectrum exceeded 3.5%. Of the isolated pathogens, 48.8% were the only etiological agents, and microbial associations were detected in 51.2% of the isolated pathogens.</p> <p><bold>Results.<italic> </italic></bold>A total of 10,327 bacteria strains were identified over the 12-year period. The leading microorganisms causing orthopedic infection were <italic>Staphylococcus</italic> spp., <italic>Enterococcus</italic> spp., <italic>Propionibacterium</italic> spp., <italic>Pseudomonas aeruginosa</italic>, <italic>Corynebacterium</italic> spp., <italic>Streptococcus</italic> spp., <italic>Klebsiella</italic> spp. and <italic>Acinetobacter</italic> spp. In the dynamics of isolated pathogens during the analyzed period, several trends were determined: a decrease in the shares of <italic>S. aureus, Enterococcus</italic> spp., <italic>P. aeruginosa</italic>, <italic>Acinetobacter</italic> spp. and an increase in the shares of CoNS and <italic>Corynebacterium</italic> spp.</p> <p><bold>Conclusion.<italic> </italic></bold>During 12 years, in the microbial spectrum of orthopedic infection in patients of the septic surgery department of our Center, Gram-positive bacteria, in the majority representatives of the genus <italic>Staphylococcus</italic>, prevailed. At the same time, a significant decrease in the share of <italic>S. aureus</italic> strains and an increase in the frequency of isolation of various species of CoNS were registered. A significant decrease in the number of non-fermenting Gram-negative bacteria was also revealed.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.<italic> </italic></bold>Количество хирургических вмешательств на опорно-двигательном аппарате возрастает с каждым годом. Одновременно с ростом доступности ортопедической помощи увеличивается и количество пациентов с ортопедической инфекцией, этиологическими агентами которой могут быть представители различных таксономических групп. <italic>Staphylococcus aureus</italic> и различные виды коагулазонегативных стафилококков (CoNS), включая <italic>S. epidermidis </italic>и <italic>S. lugdunensis</italic>, в совокупности являются возбудителями в 70% случаев.</p> <p><bold>Цель исследования</bold> — проанализировать динамику спектра ведущих патогенов, выделенных от пациентов отделения гнойной остеологии, за период с 2011 по 2022 г.</p> <p><bold>Материал и методы.<italic> </italic></bold>Выполнен ретроспективный анализ спектра микроорганизмов, изолированных от пациентов, находившихся на лечении в отделении гнойной хирургии с 1 января 2011 г. по 31 декабря 2022 г. К ведущим возбудителям относили микроорганизмы, доля которых в спектре превышала 3,5%. Из выделенных возбудителей 48,8% были единственными этиологическими агентами, в 51,2% определяли наличие микробных ассоциаций.</p> <p><bold>Результаты.<italic> </italic></bold>За 12-летний период идентифицировано 10 327 штаммов различных видов бактерий. Ведущими микроорганизмами, выделенными от пациентов с ортопедической инфекцией, были <italic>Staphylococcus</italic> spp., <italic>Enterococcus</italic> spp, <italic>Propionibacterium</italic> spp., <italic>Pseudomonas aeruginosa</italic>, <italic>Corynebacterium</italic> spp., <italic>Streptococcus</italic> spp., <italic>Klebsiella</italic> spp. и <italic>Acinetobacter</italic> spp. В динамике выделенных возбудителей за анализируемый период определено несколько трендов: сокращение долей <italic>S. aureus, Enterococcus</italic> spp., <italic>P. aeruginosa, Acinetobacter</italic> spp. и увеличение доли СоNS и <italic>Corynebacterium</italic> spp.</p> <p><bold>Заключение.</bold> Выполненное исследование показало, что в течение 12 лет в спектре возбудителей ортопедической инфекции у пациентов отделения гнойной хирургии нашего Центра основными были грамположительные бактерии, в большинстве представители рода <italic>Staphylococcus</italic>. При этом регистрировали значимое снижение доли штаммов <italic>S. aureus </italic>и рост частоты выделения различных видов СоNS.
