RESUMO
The investigations conducted showed that the antibacterial effect of dinitro-o-cresol, cuprozane, and trichlorfon is due to their chemical structure and to the species of microorganisms on which they act. Dinitro-o-cresol and Cuprozane possess selective toxicity with respect to B. anthracis and Rh. gracilis and cuprozane with respect to Ch. perfringens. The method of evaluating the effect of combinations of chemical compounds consisting of two or more components which have been developed made it possible to detect the antibacterial effect of mixtures consisting of the indicated pesticides. It was established that the combinations studied possess synergic and additive effects, which also depend on the chemical structure of the pesticides and the species of microorganisms.
