MICROBIOTA OF THE AIR ENVIRONMENT OF THE MEDICAL ORGANIZATION

The hospital environment is one of the most favorable environments for the colonization of air and environmental objects by various microorganisms. In the hospital environment of medical organizations (MO) from patients fall pathogens of infectious diseases. The purpose of the work is to study the features of the air microflora in the premises of a MO, where air samples should meet sanitary and hygienic standards for microbiological indicators. Material and methods. All types of isolated microorganisms were identified by mass spectrometry and sequencing in air samples (n=22) taken in the premises of the MO. Results. A wide species diversity of fungi and bacteria belonging to opportunistic pathogens and causing infections associated with the provision of medical care has been established. In most rooms of the MO there were Micrococcus spp. (75.0% of cases) including Kocuria kristinae (12.5%), Acinetobacter spp. (12.5%) and Stenotrophomonas maltophilia (25.0%), Neisseria flava (12.5%), Penicillium spp. (12.5%), Alternaria spp. (43.8%), Cladosporium spp. (31.3%), Aspergillus spp. (18.8%), Acremonium spp. (25.0%), Stemphylium spp., Neurospora spp., Trichoderma spp. (6.3%). Discussion. The results obtained in the study are consistent with the literature data and indicate the presence of pathogens of hospital infections and allergic diseases in the air of MO, that causes some caution and requires quality control of disinfection measures in MO. Conclusion. In the air of the MO, pathogens of infections associated with the provision of medical care, belonging to the 3-4 group of pathogenicity, were found. This dictates the need to improve measures to monitor infections associated with the provision of medical care caused by pathogens of bacterial and fungal nature.
