На протяжении десятилетий многие аспекты аэрозольной передачи больничных патогенов были и остаются предметом научных дискуссий. Несмотря на достаточно подробные исследования механизма формирования микробных аэрозолей, закономерности их распространения, роль пылевых частиц в формировании госпитальных клонов микроорганизмов не изучена. Цель. Исследовать физико-химические свойства и микробное разнообразие больничной пыли. Материалы и методы. Форма и размерность пылевых частиц проанализированы методами сканирующей электронной микроскопии и динамического рассеяния света, элементный анализ проведен посредством энергодисперсионной рентгеновской спектроскопии и высокотемпературного каталитического окисления, микробиологический состав пыли изучен при помощи полимеразной цепной реакции и биохимического анализатора Vitek 2. Результаты и обсуждение. Выявлено, что больничная пыль включает глобулярные и волокнистые частицы, в состав которых входят углерод, кислород, кальций, кремний, алюминий и сера, при этом волокнистая пыль характеризовалась повышенным содержанием кислорода и кальция и более низким уровнем углерода в минеральной, но не в органической компоненте. Картирование химических элементов позволило установить, что в состав пыли входят алюмосиликаты и соединения кальция, поскольку кремний и кальций располагались практически независимо друг от друга в виде локальных включений. Микробиологический анализ обнаружил в больничной пыли резистентные к различным антибиотикам Raoultella ornithinolytica, Staphylococcus pseudintermedius, Pantoea spp., Pseudomonas aeruginosa, Enterococcus faecium, а также Pasteurella canis. Выводы. Больничная пыль может играть существенную роль в сохранении мультирезистентных штаммов возбудителей инфекций, связанных с оказанием медицинской помощи, и формировании госпитальных клонов. Влияние морфологии пылевых частиц и химической структуры на процессы селекции госпитальных штаммов требует дальнейшего изучения.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. For decades, many aspects of aerosol transmission of hospital pathogens have been and remain the subject of scientific debate. Despite fairly detailed studies of the mechanism of microbial aerosols formation, distribution, the role of particulate matter in the formation of antibiotic resistance and multidrug-resistant hospital clones of microorganisms is still unclear. Aim. To investigate physicochemical properties and microbiological diversity of hospital particulate matter. Materials and Methods. Shape and size of particulates was assessed by means of scanning electron microscopy and dynamic light scattering while elemental analysis was performed using energy-dispersive X-ray spectroscopy and high-temperature catalytic oxidation. Microbial profiling was conducted using polymerase chain reaction and Vitek 2 biochemical analyzer. Results. Hospital particulate matter included globular and fibrillary particles consisting of carbon, oxygen, calcium, silicon, aluminium, and sulfur. Intriguingly, microfiber particles had higher oxygen and calcium content along with the lower level of carbon in mineral but not organic component. Differential localisation of silicon and calcium in elemental mapping suggested that hospital particulate matter was composed of aluminosilicate minerals and calcium compounds. Among the microorganisms, we found multidrug-resistant strains Raoultella ornithinolytica, Staphylococcus pseudintermedius, Pantoea spp., Pseudomonas aeruginosa, Enterococcus faecium and additionally Pasteurella canis in hospital particulate matter samples. Conclusions. Particulate matter in the hospital environment might be considered as a potential reservoir for the evolution of antibiotic resistance and multidrug-resistant strains.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пылевое загрязнение</kwd><kwd>мелкодисперсные взвешенные вещества</kwd><kwd>больничная пыль</kwd><kwd>инфекции</kwd><kwd>связанные с оказанием медицинской помощи</kwd><kwd>резервуар</kwd><kwd>госпитальный штамм Конфликт интересов не заявлен</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Air pollution</kwd><kwd>particulate matter</kwd><kwd>hospital environment</kwd><kwd>healthcare-associated infections</kwd><kwd>reservoir</kwd><kwd>multidrug-resistant organisms</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">Beggs C.B.
