Evaluation of antibacterial properties of ethanol and oil extracts of propolis in Kurdistan Province, on Staphylococcus epidermidis, Streptococcus mutans and Entrobacter aerogenes

Propolis is one of the most important bee products used as a natural antibiotic alternative for industrial antibiotic production in order to reduce unnecessary usage of antibiotics. The chemical structure of this natural product in different regions of the world is different. The solvent used for extraction of propolis can have a significant impact on its antimicrobial activity. The purpose of this study was to evaluate the antimicrobial properties of ethanol and oil extracts of propolis produced in Kurdistan Province on Staphylococcus epidermidis, Streptococcus mutans and Entrobacter aerogenes.
Material and After collecting propolis from different parts of Kurdistan Province, ethanol and oil extracts were prepared. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for the three above mentioned strains of bacteria were determined by using broth dilution method.
Use of alcoholic solvent (96% ethanol and dimethyl sulfoxide) resulted in a greater mean diameter of growth inhibitory zone in comparison to oil extract (p Propolis showed significant antimicrobial effects in our study therefore, it can be used in the food and pharmaceutical industries.
