Материалы и методы. Для четырех готовых лекарственных форм фторхинолонов определены минимальные ингибирующие концентрации в отношении музейных изолятов золотистого стафилококка и синегнойной палочки. Исследована кинетика роста и отмирания тест-культуры Pseudomonasaeruginosa ATCC 27853 в бульонной питательной среде в присутствии различных концентраций фторхинолонов. Результаты. Минимальные ингибирующие концентрации для различных препаратов находились в диапазоне 0,125-1,0 мкг/мл. В отношении тест-культур стафилококков большую активность проявляли препараты III поколения (МИК левофлоксацина 0,25-0,5 мкг/мл), в отношении синегнойной палочки наиболее активен ципрофлоксацин (МИК 0,125 мкг/мл). Показано, что для всех препаратов фторхинолонов выраженность бактерицидного эффекта находится в прямой зависимости от концентрации антибиотика в среде. Заключение. Выявлена сходная микробиологическая эффективность препаратов фторхинолонов II-III поколений различных производителей. Имеющиеся в составе исследованных лекарственных форм концентрации фторхинолонов позволяют достичь бактерицидного эффекта в отношении чувствительных к ним грамотрицательных микроорганизмов даже при кратковременном местном использовании. Для лечения инфекций, вызванных грамположительными возбудителями, предпочтительнее использование препаратов фторхинолонов III поколения.</p></abstract><trans-abstract xml:lang="en"><p>Goal: to find out antimicrobial efficacy of ophthalmologic drugs containing fluoroquinolons of II-III generations. Material and methods. Minimal inhibitory concentrations for isolates of Staphylococcus aureus and Pseudomonas aeruginosa were determined for four drugs containing fluoroquinolons of II-III generations. The kinetics of growth and dying off of the test-culture of Pseudomonas aeruginosa ATCC 27853 under different fluoroquinolon concentration were performed in nutrient broth medium. Results. The minimal inhibitory concentrations for various drugs ranged from 0,125 to 1,0 mcg/ml. In relation to the test-cultures of Staphylococcus aureus , III generation fluoroquinolones (levofloxacin MIC 0,25-0,5 mcg/ml) were the most active. Ciprofloxacin was the most active against Pseudomonas aeruginosa (MIC 0,125 mcg/ml). It was shown that the bacterial effect of all the fluoroquinolones depends directly on the concentration of antibiotic in the medium. Conclusion. The antimicrobial activity of II-III generation fluoroquinolones from different producers was similar. The concentration of fluoroquinolones in the studied drugs makes it possible to achieve the bactericidal effect for sensitive gram-negative strains, even after short-term exposure. It is preferable to use III generation fluoroquinolones to treat for infections caused by gram-positive microorganisms</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фторхинолоны</kwd><kwd>минимальная ингибирующая концентрация</kwd><kwd>конъюнктивит</kwd><kwd>синегнойная палочка</kwd><kwd>стафилококк</kwd><kwd>fluoroquinolones</kwd><kwd>minimal inhibitory concentration</kwd><kwd>conjunctivitis</kwd><kwd>Pseudomonas aeruginosa</kwd><kwd>Staphylococcus</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">Практическое руководство по антимикробной химиотерапии / под ред.
