ABSTRACT:
Sour cherry is a plant traditionally used as food. Its health care potency has been discovered recently. In this study, we have investigated the antimicrobial activity of sour cherry towards different pathogens by micro dilution method according to Clinical and Laboratory Standards Institute (CLSI). The chemical composition of dried juice and ethanol extract was determined by High performance liquid chromatography method. Results showed that juice and extract exhibit antibacterial activity, but have no antifungal and antialgal activity against tested pathogens.  In terms of break point, better results were obtained against Gram positive bacteria. Rhodococcus equi was the most susceptible specie to both juice and extract. Juice showed better results to: Staphylococcus aureus, Pseudomonas aeruginosa, Sallmonela Typhymurium and Acinetobacter lwoffi, but for all other investigated species extract showed superior activity.
