[Comparison of the methods of evaluation of the microbiological danger of antimicrobial agents by the example of oligo- and polyguanidines].

The article contains the results of comparison of the methods of evaluation of the microbiological danger of antimicrobial agents by the example of oligo- and polyguanidines. The study demonstrates that choice of an adequate study model (a bacterial or protozoa species) and exposure time depends on the characteristics of the preparation to be tested. It shows that the microbocide activity of polyguanidines should be studied on a bacterial model using long (24 hours) exposure.
