Оценить чувствительность к антибиотикам и их комбинациям штаммов K. pneumoniae и A. baumannii, выделенных от госпитализированных пациентов с инфекцией COVID-19.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для 47 штаммов A.baumannii и 51 штамма K.pneumoniae, выделенных от госпитализированных пациентов с инфекцией COVID-19, методом микроразведений в бульоне определены минимальные подавляющие концентрации (МПК) меропенема и колистина. Чувствительность к 11 комбинациям антибиотиков оценена с помощью модифицированного метода тестирования бактерицидности различных комбинаций.</p></sec><sec><title>Результаты</title><p>Результаты. Устойчивость к колистину выявлена у 31,9 % штаммов A.baumannii (МПК50 — 0,5 мг/л, МПК90 — 16 мг/л) и у 80,4 % штаммов K.pneumoniae (МПК50 — 16 мг/л, МПК 90 — 256 мг/л). Показано, что двойные комбинации антибиотиков с включением колистина проявляют бактерицидную либо бактериостатическую активности в отношении 76,6–87,2 % штаммов A.baumannii. Комбинации с включением меропенема, колистина и макролидов проявляли бактерицидную активность в отношении 78,4–80,4 % штаммов K.pneumoniae. Комбинации из двух карбапенемов были не активны, комбинация «меропенем-колистин» оказывала бактерицидное действие только на 13,7 % штаммов K.pneumoniae.</p></sec><sec><title>Заключение</title><p>Заключение. Выявлено широкое распространение устойчивости к колистину у карбапенеморезистентных штаммов K.pneumoniae и A.baumannii, выделенных от госпитализированных пациентов с инфекцией COVID-19. Определены комбинации антибиотиков, оказывающих синергидный антибактериальный эффект в своих фармакокинетических (фармакодинамических) концентрациях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To assess the susceptibility of K.pneumoniae and A.baumanii strains isolated from hospitalized COVID-19 patients to antibiotics and their combinations.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The minimum inhibitory concentrations (MICs) of meropenem and colistin were determined for 47 A.baumannii and 51K.pneumoniaestrains isolated from the hospitalized COVID-19 patients by the broth microdilution method. The susceptibility to 11 antibiotic combinations was assessed using the method of multiple combination bactericidal testing.</p></sec><sec><title>Results</title><p>Results. Colistin resistance was detected in 31.9 % of A.baumannii strains (MIC50 — 0.5 mg/l, MIC90 — 16 mg/l) and in 80.4 % of K.pneumoniaestrains (MIC50 — 16 mg/l, MIC90 — 256 mg/l). It has been shown that double antibiotic combinations with the inclusion of colistin exhibit bactericidal or bacteriostatic activity against 76.6–87.2 % of A.baumannii strains. Combinations with the addition of meropenem, colistin and macrolides exhibited bactericidal activity against 78.4–80.4 % of K.pneumoniae strains. Combinations of two carbapenems were not active, the combination of meropenem-colistin had a bactericidal effect only in 13.7 % of K.pneumoniae strains.</p></sec><sec><title>Conclusion</title><p>Conclusion. Widespread colistin resistance was found in carbapenem-resistant K.pneumoniae and A.baumannii strains isolated from the hospitalized COVID-19 patients. The combinations of antibiotics that have a synergistic antibacterial effect in their pharmacokinetic/pharmacodynamic concentrations have been determined.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Klebsiella pneumoniae</kwd><kwd>Acinetobacter baumannii</kwd><kwd>антибиотикорезистентность</kwd><kwd>комбинации антибиотиков</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Klebsiella pneumoniae</kwd><kwd>Acinetobacter baumannii</kwd><kwd>antibiotic resistance</kwd><kwd>antibiotic combinations</kwd><kwd>COVID-19</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Синопальников АИ.
