Abstract:
Abstract: This paper deals with study of species composition and population level of nasal and tonsillar microbiota in adults. Contamination of mucous membranes with S.aureus, S.pyogenes, S.viridans, H. influenzae, K.pneumoniae, E. coli, S. pneumoniae, fungi of Candida genus in adults infected with influenza viruses had determined. It had been established in vitro the influence alike antagonistic activity of Bacillus subtilis and Bacillus licheniformis strains towards inhibition of bacterial growth of Staphylococcus aureus, Streptococcus pyogenes strains: after 24 hours for 24,15±0,17%, after 48 hours – to 44,65±0,22% and after 72 hours – to 58,94±0,23%. Permanent antagonistic activity had appeared onto S. pyogenes also in 24 hours, gradually increased and reached up to 73,33±0,19% in 72 hours. It was observed the decreasing of population level of pathogenic and opportunistic organisms of tonsillar and nasal mucosae against the background of complete elimination of S. aureus, K. pneumonia, S. pyogenes, S.viridans, S. epidermidis, H. influenzae, S. pneumoniae, E. coli, fungi of Candida genus (p<0.05).
