[Hygienic evaluation of staphylococcal nasal mucosal biocenosis in school children of an industrial city]. / Gigienicheskaia otsenka stafilokokkovogo biotsenoza slizistoi nosa shkol'nikov promyshlennogo goroda.

The results of microbiological spatial monitoring in Orenburg were evaluated. A biological variety of Staphylococcus on the nasal mucosa of schoolchildren were detected. The highest proportion of carriage of the pathogen Staphylococcus was found in different districts of Orenburg, which had the highest air pollution.

[The characteristics of the formation of the staphylococcal landscape in the nasal mucosa of different types of bacterial carriers]. / Osobennosti formirovaniia stafilokokkovogo peizazha slizistoi nosa u bakterionositelei raznykh tipov.

The complex study of factors of persistence, virulence and antagonism in 473 coagulase-positive (CP) staphylococci and 489 coagulase-negative (CN) staphylococci inhabiting the nasal mucosa of resident and transitory carriers, and not carriers of CP staphylococci, was made. In the selection of virulent strains of CP staphylococci the factor of anti-interferon activity seemed to be of greater importance than the factor of antilysozyme activity, but the latter was preferable in the selection of virulent strains of CN staphylococci. Biovars of CP staphylococci with a set of factors of persistence, virulence and antagonism were isolated from resident carriers 1.6-3.1 times more frequently than from transitory ones. The selection of virulent biovars could be made among strains of CN staphylococci with pronounced persistent properties, isolated from subjects carrying no CP staphylococci.
