Abstract [eng] Antimicrobial properties of plant extracts were determined in vitro. Antimicrobial effects of plant extracts against Salmonella typhimurium (ATCC 14028), Escherichia coli (ATCC 25922), Bacillus subtilis and Enterococcus faecalis (ATCC 29212) were determined by an agar diffusion test. The strains of bacteria were precultured into trypticase soy broth at 37 ºС for 24 h. The extracts were tested in concentrations of 10 % and 5 %. Plates were incubated at 37 ºС for 24 h, after which the inhibition zones were measured with callipers and recorded in millimeters. All the tests were performed in triplicates. The intensity of antimicrobial efficacy was in the following order: Rozmarinus officinalis L., Levisticum officinale WDJ Koch and Petroselinum sativum Hoffm. The minimum inhibitory concentration was defined as the concentration of extracts that prevented growth in all inoculated cultures. The inoculum was 103105 CFU/ml in this experiment. To determine the MIC of extracts against test-culture, extracts were added to the test medium at concentrations ranging from 0.01 % to 1 %.
