The aim of this work was to evaluate antimicrobial properties of ethanolic extracts of plants (Mentha x piperita L., Carum carvi L., Petroselinum crispum (Mill.) A.W. Nym. ex Hill, Betula pendula Roth. and Rhamnus frangula L.) originated from Serbia. The antimicrobial activity was tested by paper disc diffusion method and by microdilution technique against six pathogenic bacteria (Bacillus Cereus ATCC 10876, Enterococcus Faecalis ATCC 14506, Salmonella Choleraesuis ATCC 10708, Staphylococcus Aureus ATCC 11632, Proteus Mirabilis ATCC 12453 and Escherichia Coli ATCC 10536). B. cereus was the most susceptible to the extracts of M. piperita, R. frangula and B. pendula among tested microorganisms. Ethanolic extracts of Betula pendula Roth., Mentha x piperita L. and Rhamnus frangula L. have been shown to possess the strongest antimicrobial activity against Bacillus Cereus, where the minimum inhibitory concentrations were 10 mg/ml (Betula pendula Roth.) and 50 mg/ml (Mentha x piperita L. and Rhamnus frangula L.) The highest antibacterial potential was exibited by ethanolic extract of Mentha x piperita L., followed by Rhamnus frangula L. and Betula pendula Roth. Contrary to this, the extracts of Carum carvi L. and Petroselinum crispum (Mill.) A.W. Nym. ex Hill did not show significant antimicrobial effects towards investigated bacteria.
