Abstract: The aim of this project was to determine the antimicrobial activity of honeys produced in the Czech Republic to some bacteria (Listeria monocytogenes, Staphylococcus aureus, Salmonella typhimurium and Escherichia coli). Another aim was to find out whether there are correlations between the antimicrobial activity of honeys and their physicochemical parameters. All honeys included in the study were directly obtained from beekeepers in Southern and Northern Moravia from the summer load of 2001. The project contains 20 honeys which were determined according to their conductivity as blossom (6), blends (10) and honeydew (4). The determination of physical and chemical parameters such as content of water, conductivity, pH, water activity, invertase and diastase activities was carried out in accordance with the methods described in Harmonised methods of the European Honey Commission. The determination of the antimicrobial activity of honey was done by the MIC (minimal inhibitory concentration) method. Statistically significant relations between the antimicrobial activity and the conductivity of honey (P < 0.05), the diastase (P < 0.05) and invertase (P < 0.001) activities were found out in the observed physicochemical parameters. The study proved that honey produced in the Czech Republic is antimicrobially effective with the highest effect in honeydew honeys (P < 0.01).
