Biological properties of staphylococci, isolated from school children living in ecologically contrasting regions, have been studied; and analysis of air pollution in given populated areas has been carried out. More informative biological characteristics for staphylococci and priority

factors of environmental pollution have been determined. On the basis of integrated hygienic and microbiological data, mathematical adaptive

model has been proposed, which evaluates the probability of illness development in children of junior school age in settlements with various air pollution conditions.

The average level of staphylococcal bacterial carriage (a), pollution

of the air environment (b) and the general disease of illnesses of

respiratory organs (c) on ecologically contrast areas (1,2) of the

Orenburg region.

An integrated medical and biological approach takes into account indicators in the system «technogenic pollution→automicroflora properties→illnesses of respiratory organs»; this approach is based on the biological properties of automicroflora, which change depending on the prevailing air pollutants. Novelty is provided by the selected complex of informative characteristics and their integrated analysis. Application field is the public health.
