Abstract

Propolis alcoholic tincture is most commonly used propolis product on the market for the treatment of minor infections in the oral cavity; angina, some skin diseases etc. As propolis is still an unofficial drug in pharmacies, we tested its antimicrobial activity using a disk-diffusion test on six reference bacterial species-Salmonella Enterica WDCM 00030, Salmonella typhimurium WDCM 00031, Listeria monocytogenes WDCM 00020, Staphylococcus aureus WDCM 00032, Escherichia coli WDCM 00013 and Pseudomonas aeruginosa WDCM 00024.

The aim of this paper was to examine the antibacterial action of alcoholic solution of propolis on reference bacterial cultures and to determine the type of action. Based on the obtained results, it can be concluded that the bacterial strains of Salmonella Enteritidis WDCM 00030, Salmonella Typhimurium WDCM 00031, Listeria monocytogenes WDCM 00020, Staphylococcus aureus WDCM 00032 and Pseudomonas aeruginosa WDCM 00024 are highly sensitive to the action of propolis alcoholic tincture.
