[Symbiotic interactions of microorganisms during infection].

Symbiotic interactions of microorganisms during infection are reviewed. Infectious process is presented as a model system of associative symbiosis with 3 functional vectors of symbiont interactions. The principal attention is paid to microsymbiocenosis and estimation of its role during infection. Materials on population-communicative dialogue of microsymbionts are given, and their applied importance for medical-biological science is shown. Algorithm of microbial "self-non self" recognition under the control of opposite (increase/ suppression) effect of dominant-associant microbe pair on principal physiological (growth and persistence) functions of microsymbionts is presented.
