Изучено действие лизостафина в отношении 120 клинических (30 MSSA, 30 MRSA, 30 MSSE, 30 MRSE) и 4 эталонных штаммов стафилококков. МИК лизостафина определяли методом серийных разведений (0,06 до 512 мг/л). Влияние на биопленкообразование и биопленки оценивали по методу O'Toole. Анализ данных выполняли в GraphPad Prism.</p></sec><sec><title>   Результаты</title><p>   Результаты. Показано, что лизостафин был в 2 раза активнее в отношении чувствительных к метициллину штаммов, а также активнее в отношении S. aureus, чем против S. epidermidis. Изученные концентрации лизостафина эффективно предотвращали образование биопленок, более эффективно у штаммов MSSA. Показатель MBIC90 лизостафина определен в 4 раза выше для MRSE и в два раза выше для штаммов S. aureus. Показатель MBEC90 лизостафина в отношении S. epidermidis был в 32 раза выше, чем для культур S. aureus.</p></sec><sec><title>   Заключение</title><p>   Заключение. Выраженное антистафилококковое действие лизостафина, а также его активное деструктивное действие на биопленки S. aureus представляют особый интерес для дальнейшего изучения и внедрения в клиническую практику для борьбы со стафилококковой инфекцией, в том числе связанной с различными имплантатами в ортопедии, стоматологии, кардиологии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Objective</title><p>   Objective. To conduct a comparative evaluation of lysostaphin activity against isolates of S. aureus, S. epidermidis and their biofilms, obtained from orthopedic patients.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. The study examines the effect of lysostaphin on 120 clinical bacterial isolates (30 MSSA, 30 MRSA, 30 MSSE, and 30 MRSE) alongside four reference strains of staphylococci. The minimum inhibitory concentration of lysostaphin was determined using a serial dilution method (ranging from 0.06 to 512 mg/l). The effect on biofilms and their formation was assessed by means of the O'Toole method. Data analysis was performed using GraphPad Prism software.</p></sec><sec><title>   Results</title><p>   Results. According to the results, lysostaphin exhibited twice the activity against methicillin-sensitive strains and was more effective against S. aureus compared to S. epidermidis. The studied concentrations of lysostaphin effectively prevented biofilm formation, particularly in MSSA strains. The MBIC90 value for lysostaphin was found to be four times higher for MRSE strains and twice as high for S. aureus. Additionally, the MBEC90 value of lysostaphin against S. epidermidis was 32 times greater than that observed for S. aureus.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The pronounced anti-staphylococcal activity of lysostaphin, along with its significant destructive effect on S. aureus biofilms, offers a considerable potential for further investigation and implementation in clinical practice to combat staphylococcal infections, including those associated with various implants in orthopedics, dentistry, and cardiology.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>S. aureus</kwd><kwd>S. epidermidis</kwd><kwd>лизостафин</kwd><kwd>биопленка</kwd><kwd>антибиотикорезистентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>S. aureus</kwd><kwd>S. epidermidis</kwd><kwd>lysostaphin</kwd><kwd>biofilm</kwd><kwd>antibiotic resistance</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Научное исследование выполнено в рамках реализации государственного задания № 056-00123-21-00</funding-statement><funding-statement xml:lang="en">The scientific research was carried out as part of the implementation of a state assignment No. 056-00123-21-00</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chen H, Zhang J, He Y, Lv Z, Liang Z, Chen J, et al.
