[Study of nasal and tonsillar mucosal microbiocenoses as one of the health indices].

The qualitative and quantitative compositions of nasal and tonsillar mucosal biocenoses were studied in healthy individuals and patients with chronic tonsillitis as an ecological criterion for assessing the stability of biocenosis and human health. The qualitative composition of tonsillar mucosal biocenosis turned out to be steady-state both in health and disease. The human nasal mucosa showed itself as an indicator system. Staphylococcal strains with a high persistent potential and polyantibiotic resistance, which may cause an exacerbation of the inflammatory process on translocation to the tonsillar mucosa, were selected on the nasal mucosa of patients with chronic tonsillitis.
