Совокупность факторов распространенности глазных инфекционно-воспалительных заболеваний, антибиотикорезистентности и внутренние мутации самих возбудителей обостряют необходимость поиска высокоэффективных альтернатив в борьбе с глазными инфекционными заболеваниями. Особый интерес представляют перспективы применения флуоресцентных полупроводниковых нанокристаллов, называемых квантовыми точками, в лечении резистентных инфекционных воспалительных заболеваний. Задачей исследования явилась оценка антиинфекционной активности биоконъюгатов на основе квантовых точек CdTe/Cd MPA 710 и левофлоксацина в отношении стафилококковой инфекции роговицы на примере индуцированного инфекционного кератита у лабораторных животных. В качестве объекта исследования изучены 6 самцов (6 глаз) новозеландских кроликов, которым производили индукцию бактериального кератита путем введения госпитального штамма S. Aureus в структуры роговицы. В качестве противомикробных средств были использованы: раствор левофлоксацина 5 мл для эпибульбарного применения и биоконъюгат на основе КТ CdTe/Cd MPA 710 и левофлоксацина. Лабораторных животных разделили на 2 группы. Кролики 1-й группы после манифестации клинической картины бактериального кератита получали инстилляции капель левофлоксацина в конъюнктивальный мешок каждые 2 часа на протяжении 7 дней, кролики 2-й группы по той же схеме лечения получали инстилляции биоконъюгата. В качестве методов динамического наблюдения использовали фоторегистрацию переднего отрезка глаза с окрашиванием флуоресцеином и оптическую когерентную томографию. В данном клиническом эксперименте биоконъюгат на основе КТ CdTe/Cd MPA 710 и левофлоксацина продемонстрировал более выраженную клиническую эффективность в отношении госпитального штама S. Aureus в сравнении с монотерапией левофлоксацином.</p></abstract><trans-abstract xml:lang="en"><p>Infectious keratitis is one of the leading causes of persistent decline in visual function and monocular blindness in both developed and developing countries. The combination of factors in the prevalence of eye infectious and inflammatory diseases, antibiotic resistance, and internal mutations of the pathogens themselves exacerbate the need to search for highly effective alternatives in the fight against eye infectious diseases. Of particular interest are the prospects for the use of fluorescent semiconductor nanocrystals, called quantum dots, in the treatment of resistant infectious inflammatory diseases. The objective of the study was to assess the anti-infectious activity of bioconjugates based on CdTe / Cd MPA 710 quantum dots and levofloxacin against staphylococcal corneal infection using the example induced infectious keratitis in laboratory animals. As the object of the study, 6 male (6 eyes) New Zealand rabbits were studied, which underwent induction of bacterial keratitis by introducing a hospital strain of S. Aureus into the structure of the cornea. The following were used as antimicrobial agents: a solution of levofloxacin 5 ml for epibulbar use and a bioconjugate based on CT CdTe / Cd MPA 710 and levofloxacin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бактериальный кератит</kwd><kwd>роговица</kwd><kwd>квантовые точки</kwd><kwd>антибиотики</kwd><kwd>биоконъюгаты</kwd><kwd>эффективность</kwd><kwd>резистентность</kwd><kwd>левофлоксацин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bacterial keratitis</kwd><kwd>cornea</kwd><kwd>quantum dots</kwd><kwd>antibiotics</kwd><kwd>bioconjugates</kwd><kwd>efficacy</kwd><kwd>resistance</kwd><kwd>levofloxacin</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">Flaxman S.R., Bourne R.R.A., Resnikoff S.
