Wide and not always rational use of chemical disinfectants carries risks for the safety of the environment, the patient and medical staff. In this regard, there remains the search for alternative methods of purification and decontamination of abiotic surfaces in health care facilities. Tested the tool for cleaning areas that contain 3 strains of the genus Bacillus: B. subtillis, B. licheniformis, B. pumilus. Were treated areas of the medical centre in St. Petersburg Pasteur Institute: the treatment room (experience) and the office of the gynecologist (control with conventional cleaning and disinfection). Within 30 days of the sowing of samples of swabs from surfaces were made of 3 Petri dishes with the “blood” agar-based environment “agar of Givental–Witch” debilitating touch (gold method). Isolated cultures of bacteria identified by microscopy, biochemical typing and MALDI-TOF MS (Bruker). In control and the experience in the 1st day of observation prior to the cleaning sown Enterococcus faecium 10<sup>4</sup> –10<sup>5</sup> CFU/ml. The 2nd day of observation in the control was dominated by E. faecium, then his growth stopped. For the 2nd–4th day watched the growth of Enterobacteriaceae to 10<sup>6</sup> CFU/ml, in the future, the number was 10 CFU/ml until the end of the observation period (30 days). The 5th day in the control revealed the growth of bacteria of the genus Staphylococcus spp. mainly S. epidermidis. The experience from the 2nd day of observation revealed a significant increase in Bacillus spp. at 10<sup>5</sup> CFU/ml, then before the end of the experiment, the number was 10<sup>2</sup> –10<sup>3</sup> CFU/ml. In the 1st–2nd day revealed growth of E. faecium, and then it stopped. For the 2nd–4th day watched the growth of Enterobacteriaceae to the level of 10<sup>6</sup> CFU/ml, on the 8th day — to 10<sup>2</sup> CFU/ml, the growth of conditionally pathogenic microflora was absent. Cleaning of the premises on the basis of probiotic bacteria of the genus Bacillus inhibits the growth of sanitary-indicative microorganisms compared to control. Thus, the means of probiotic treatment did not have a biocidal effect, but inhabiting the surface, they inhibit the growth and proliferation of opportunistic bacteria.</p><p> </p></abstract><trans-abstract xml:lang="ru"><p>Известно, что любые поверхности окружающей среды в лечебно-профилактических организациях являются резервуаром для микроорганизмов и способствуют передаче патогенов, увеличивая риск перекрестного загрязнения через опосредованный контакт с пациентом. Широкое и не всегда рациональное использование химических дезинфицирующих средств несет риски для безопасности окружающей среды, пациента и медицинского персонала. В связи с этим актуальным остается поиск альтернативных методов очистки и обеззараживания абиотических поверхностей в учреждениях здравоохранения. Тестировали средство для очистки помещений, содержащее 3 штамма бактерий рода Bacillus: В. subtillis, В. licheniformis, В. pumilus. Про- водили обработку помещений медицинского центра ФБУН НИИ эпидемиологии и микробиологии имени Пастера: процедурного кабинета (опыт) и кабинета врача-гинеколога (контроль с обычной уборкой и дезинфекцией). В течение 30 дней посев проб смывов с поверхностей производили на 3 чашки Петри с «кровяным» агаром на основе среды «агар Гивенталя–Ведьминой» истощающим штрихом (метод Гольда). Выделенные культуры бактерий идентифицировали с помощью микроскопии, биохимического типирования и MALDITOF MS (Bruker). В контроле и опыте в 1-й день наблюдения до начала уборки помещений высевали Enterococcus faecium 10<sup>4</sup> –10<sup>5</sup> КОЕ/мл. До 2-го дня наблюдения в контроле преобладал E. faecium, затем его рост прекратился. На 2–4-й день наблюдали рост бактерий семейства Enterobacteriaceae до 10<sup>6</sup> КОЕ/мл, в дальнейшем их количество составляло 10 КОЕ/мл до конца срока наблюдения (30 дней). С 5-го дня в контроле выявляли рост бактерий рода Staphylococcus spp., в основном S. epidermidis. В опыте со 2-го дня наблюдения выявляли достоверный рост Bacillus spp. на уровне 10<sup>5</sup> КОЕ/мл, затем до конца срока эксперимента их количество составляло 10<sup>2</sup> –10<sup>3</sup> КОЕ/мл. В 1–2-й день выявляли рост E. faecium, затем он прекратился. На 2–4-й день наблюдали рост бактерий семейства Enterobacteriaceae до уровня 10<sup>6</sup> КОЕ/мл и на 8-й день — до 10<sup>2</sup> КОЕ/мл, в остальные дни рост условно-патогенной микробиоты отсутствовал. Средство для очистки помещений на основе пробиотиков — бактерий рода Bacillus — сдерживает рост санитарно-показательных микроорганизмов по сравнению с контролем. Таким образом, средства пробиотической очистки не обладают биоцидным действием, но, контаминируя поверхности, они подавляют рост и распространение условно-патогенных бактерий.</p><p> </p></trans-abstract><kwd-group xml:lang="en"><kwd>probiotics</kwd><kwd>probiotic sanitation</kwd><kwd>chemical disinfectants</kwd><kwd>surface sanitation</kwd><kwd>resistance of pathogens to disinfectants</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пробиотики</kwd><kwd>пробиотическая очистка</kwd><kwd>химические дезинфектанты</kwd><kwd>очистка поверхностей</kwd><kwd>устойчивость патогенов к дезинфектантам</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.Коза Н.М.
