Objective:To determine the antimicrobial activity of rosemary(Rosmarinus of ficinalis L.) and to investigate the synergistic effects of this extract combined with ceforuxime against methicillinresistant Staphylococcus aureus(MRSA).Methods:The inhibitory and bactericidal activities of rosemary ethanol extract,alone and in combination with cefuroxime,were studied.Results:The minimum inhibitory concentrations(MICs) of the ethanol extract of rosemary were in the range of 0.39-3.13 mg/mL.The minimum bactericidal concentrations(MBCs) were usually equal to or double that MICs.The antimicrobial activity of combinations of the ethanol extract of rosemary and cefuroxime indicated their synergistic effects against all MRSAs.Conclusions:The present work clearly demonstrates that rosemary has a key role in the elevation of susceptibility toβ-lactams.
