Objective: To explore the in vitro antibacterial activity of ethanolic extracts of cinnamon (Cinnamomum zeylanicum; CIN), clove (Syzygium aromaticum, CLV) and cumin (Cuminum cyminum, CMN) against clinical isolates of methicillin resistant Staphylococcus aureus (MRSA), from Kolkata, India.
Methods: The CIN, CLV and CMN were tested for their antibacterial activity against MRSA by in vitro methods. Minimum inhibitory concentration (MIC) values of the three extracts were determined, and time-kill studies were performed in order to investigate the bactericidal activity of the extracts (at the MIC level) for the isolates.
