The total bacterial contamination, the content of staphylococci and mold spores were determined. Ozonation of the room (83.3 m3) was carried out for 20 minutes by means of domestic ozonator. The accumulated dose of ozone was 133.3 mg (1.6 mg/m3). Statistical data processing was carried out using the MedStat licensed program. The median, median error (Me ± me), left and right 95 % confidence intervals (95 % CI) were calculated. Paired comparisons were made using Wilcoxon's T-test.</p> <p><bold>Results.</bold> After the meeting, the total bacterial contamination of the air was 56.0 ± 9.3 (47.0–78.0) CFU. The content of staphylococci and mold spores in the air was 85.5 ± 12.5 (76.0–100.0) and 44.5 ± 6.5 (32.0–54.0) CFU, respectively. After ozonation, the total bacterial contamination of the air was 14.5 ± 3.6 (10.0–21.0) CFU. The content of staphylococci and mold spores in the air after ozonation was 35.5 ± 6.7 (25.0–52.0) and 26.0 ± 5.0 (18.0–32.0) CFU, respectively. Ozonation of the room provided a significant decrease (p &lt; 0.001) in all three of the above indicators. The room ozonation carried out promoted a reliable decrease (p &lt; 0.001) in all the above mentioned parameters.</p> <p><bold>Conclusions</bold>. The above data and analysis of the literature show the possibility of using low doses of ozone for the prevention of bacterial, fungal and viral infections including SARS-CoV-2. Further study and development of reasonable modes of ozone disinfection, including low doses of ozone, is needed, as well as determination of the efficiency degree of air disinfection with non-toxic gas concentrations.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Оценить эффективность озонирования воздуха в низких дозах для дезинфекции воздушной среды рабочего помещения.</p> <p><bold>Материал и методы.</bold> Исследованы 90 проб воздуха (еженедельно устройством автоматического отбора проб биологических аэрозолей воздуха ПУ-1Б отбирались по три образца до и после производственного совещания). Определялись: общая бактериальная обсемененность, содержание стафилококков и спор плесневых грибов. Озонирование помещения (83,3 м3) проводилось в течение 20 мин бытовым озонатором. Накопленная доза озона составила 133,3 мг (1,6 мг/м3). Статистическая обработка данных осуществлялась с использованием лицензионной программы MedStat. Рассчитаны медиана, ошибка медианы (Me ± me), левый и правый 95%-ный доверительные интервалы (95 % ДИ). Выполнены парные сравнения с использованием T-критерия Вилкоксона.</p> <p><bold>Результаты.</bold> После совещания общая бактериальная обсемененность воздуха составила 56,0 ± 9,3 (47,0–78,0) КОЕ. Содержание в воздухе стафилококков и спор плесневых грибов равнялось соответственно 85,5 ± 12,5 (76,0–100,0) и 44,5 ± 6,5 (32,0–54,0) КОЕ. После проведения озонирования общая бактериальная обсемененность воздуха составила 14,5 ± 3,6 (10,0–21,0) КОЕ. Содержание в воздухе стафилококков и спор плесневых грибов после озонирования составило 35,5 ± 6,7 (25,0–52,0) и 26,0 ± 5,0 (18,0–32,0) КОЕ соответственно. Проведение зонирования помещения обеспечило достоверное снижение (р &lt; 0,001) всех трех вышеупомянутых показателей.</p> <p><bold>Выводы.</bold> Вышеуказанные данные и анализ литературы показывают возможность использования низких доз озона для профилактики бактериальных, грибковых и вирусных инфекций, в том числе SARS-CoV-2. Необходимо дальнейшее изучение и разработка обоснованных режимов дезинфекции озоном, в том числе и его низкими дозами, а также определение степени эффективности обеззараживания воздуха нетоксичными концентрациями газа.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ozone</kwd><kwd>air</kwd><kwd>working room</kwd><kwd>disinfection</kwd><kwd>prevention</kwd><kwd>bacteria</kwd><kwd>mold spores</kwd><kwd>SARS-CoV-2</kwd><kwd>coronavirus</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Озон</kwd><kwd>воздух</kwd><kwd>рабочее помещение</kwd><kwd>дезинфекция</kwd><kwd>профилактика</kwd><kwd>бактерии</kwd><kwd>споры плесневых грибов</kwd><kwd>SARS-CoV-2</kwd><kwd>коронавирус</kwd><kwd>COVID-19</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Kemp S.J., Kuehn T.H., Pui D.Y.H., Vesley D., Streifel A.J.
