Influence of Tularemia Microbe of Different Subspecies on the Functional Activity of Immunocompetent Cells of Experimental Animals

Analysis of molecular-biological mechanisms of patho-, immuno- and morphogenesis allowed to determine the role of bactericidal mechanisms (oxygen-, nitroxide-related and oxygen-free) of tularemia microbe phagocytosis by immunophagocytic system cells. Using PCR with primers pdpD-1F, pdpD-1R, pdpA 1, pdpA2 it was shown that the structure of pathogenicity islands (FPI) in F. tularensis strains of different subspecies depended upon what subspecies the strain belonged to, and was probably associated with tularemia microbe virulence. The macroorganism reaction to the introduction of tularemia microbe of different subspecies was evaluated. The obtained data were of prognostic significance for characterization of infectious process course and for the development of criteria for lymphoid organs response in pathologic and adaptive processes.
