Материал и методы. Методом серийных разведений в бульоне определены минимальные подавляющие концентрации (МПК) ацетонового экстракта H. physodes для референсных и клинических изолятов Enterococcus faecalis . Оценку эффективности комбинированного воздействия экстракта H. physodes в сочетании с антибиотиками проводили с использованием модифицированного диско-диффузионного метода и метода «шахматной доски». Результаты. Выявлена выраженная антибактериальная активность (МПК 32-64 мкг/мл) ацетонового экстракта H. physodes в отношении ванкомициночувствительных и ванкомицинорезистентных штаммов энтерококков. Обнаружен синергидный эффект (ΣФПК от 0,125 до 0,375) комбинации экстракта H. physodes и аминогликозидов в отношении E. faecalis , включая ванкомицинорезистентные штаммы. Заключение. H. physodes является перспективным источником соединений с антибактериальной активностью, требуется проведение дальнейших исследований для идентификации и выделения из состава экстракта лишайника вторичного метаболита, обладающего синергидной активностью в сочетании с аминогликозидами.</p></abstract><trans-abstract xml:lang="en"><p>Objective : to study antibacterial properties of Hypogymnia physodes extract and its combinations with antibiotics against vancomycin-sensitive and vancomycin-resistant strains of enterococci. Material and methods. Minimum inhibitory concentrations (MICs) of the acetone extract of H. physodes for reference and clinical isolates of Enterococcus faecalis were determined by the serial broth dilution method. Evaluation of efficiency of the combined effect of the H. physodes extract in combination with antibiotics was carried out using the modified disc-diffusion method and «chessboard» method. Results. We have revealed marked antibacterial activity (MIC 32-64 mcg/ml) of the acetone extract of H. physodes against vancomycin-sensitive and vancomycin-resistant strains of enterococci and found a synergistic effect (ΣFIC from 0.125 to 0.375) of the combination of the H. physodes extract and aminoglycosides against E. faecalis , including vancomycin-resistant strains. Conclusion. H. physodes is a promising source of compounds with antibacterial activity, further research is required to identify and isolate a secondary metabolite having synergistic activity in combination with aminoglycosides from the lichen extract.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>энтерококки</kwd><kwd>аминогликозиды</kwd><kwd>синергизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hypogymnia physodes</kwd><kwd>enterococci</kwd><kwd>Hypogymnia physodes</kwd><kwd>aminoglycosides</kwd><kwd>synergism</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">Isenman H, Fisher D.
