Methods for the study of antibiotic resistance of clinical isolates of <italic>S. aureus</italic>: disk diffusion method, method for determining the beta-lactamase activity of bacterial suspension using the "BioLactam" test system.</p> <p><bold>Results. </bold>It was found, that 80.6% of the therapeutic isolates and 73.2% of the surgical isolates were resistant to the 1st generation penicillins. 5.4% of therapeutic isolates and 34% of surgical isolates were resistant to inhibitor-protected beta-lactams. 36.8% of surgical isolates and no therapeutic isolates were resistant to cephalosporins of the 3rd generation. No MRSA were detected among the therapeutic isolates, and among the surgical isolates the prevalence of MRSA was 30.5%. 93.3% of therapeutic isolates of <italic>S. aureus</italic> did not show any beta-lactamase activity. Among surgical isolates there were only 34.4% of such isolates. Direct Spearman’s correlations of moderate strength were revealed between the levels of beta-lactamase activity of <italic>S. aureus</italic> isolates, the duration of hospitalization and febrile period, as well as between the isolation of MRSA and the duration of hospitalization, fever and diarrheal syndrome.</p> <p><bold>Conclusion. </bold>The use of inhibitor-protected penicillins and 3rd generation cephalosporins is recommended for empirical antibiotic therapy of "therapeutic" infections caused by <italic>S. aureus</italic>. Reserve antibiotics with selective antistaphylococcal activity (such as glycopeptides or oxazolidinones) are required for empirical antibacterial therapy of staphylococcal infections in surgical departments and resuscitation units</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель </bold>– выявить особенности устойчивости к бета-лактамным антибиотикам клинических изолятов <italic>S. aureus</italic>, выделенных в стационарах различного профиля, а также скорректировать рекомендации по эмпирической этиотропной терапии, назначаемой пациентам со стафилококковыми инфекциями.</p> <p><bold>Материал и методы.</bold> Объектом исследования являются клинические изоляты <italic>S. aureus</italic>, выделенные от пациентов, госпитализированных в Витебскую областную клиническую инфекционную больницу («терапевтические» изоляты, n=117) и отделение гнойной хирургии и ОРИТ Витебской областной клинической больницы («хирургические» изоляты, n=111) в 2016–17 гг. Методы исследования антибиотикорезистентности клинических изолятов <italic>S. aureus</italic>: диско-диффузионный метод, метод определения бета-лактамазной активности бактериальной взвеси с помощью тест-системы «БиоЛактам».</p> <p><bold>Результаты.</bold> Оказалось, что 80,6% терапевтических изолятов и 73,2% хирургических изолятов устойчивы к пенициллинам 1 поколения. К ингибитор-защищенным бета-лактамам были устойчивы 5,4% терапевтических изолятов и 34% хирургических изолятов. К цефалоспоринам 3 поколения были устойчивы 36,8% хирургических изолятов и ни одного терапевтического изолята. Среди терапевтических изолятов не было выявлено ни одного MRSA, а среди хирургических изолятов распространенность MRSA составила 30,5%. 93,3% терапевтических изолятов <italic>S. aureus</italic> не проявляли бета-лактамазной активности. Среди хирургических изолятов таких оказалось всего 34,4%. Выявлены прямые корреляции средней силы между уровнями бета-лактамазной активности изолятов <italic>S. aureus</italic>, длительностью госпитализации и продолжительностью лихорадочного периода, а также между выявлением MRSA и длительностью госпитализации, продолжительностью лихорадки и диарейного синдрома.</p> <p><bold>Заключение. </bold>Для эмпирической антибактериальной терапии терапевтических инфекций, вызванных <italic>S. aureus</italic>, рекомендовано использование ингибитор-защищенных пенициллинов и цефалоспоринов 3 поколения. Для эмпирической антибактериальной терапии стафилококковых инфекций хирургических и реанимационных отделений необходимы антибиотики резерва с избирательной антистафилококковой активностью, например, гликопептиды или оксазолидиноны.</p></trans-abstract><kwd-group xml:lang="en"><kwd>clinical isolates of S. aureus</kwd><kwd>antibiotic resistance</kwd><kwd>MRSA</kwd><kwd>empirical etiotropic therapy</kwd><kwd>S. aureus antibiotic resistance mechanisms</kwd><kwd>therapeutic and surgical departments of hospitals</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>клинические изоляты S. aureus</kwd><kwd>антибиотикорезистентность</kwd><kwd>MRSA</kwd><kwd>эмпирическая этиотропная терапия</kwd><kwd>механизмы антибиотикорезистентности S. aureus</kwd><kwd>терапевтические и хирургические отделения стационаров</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Schlecht LM, Peters BM, Krom BP, et al.
