Abstract
In this work, we evaluated the anti-MRSA activity of essential oils obtained from four Algerian medicinal plants
which are: Ammoides verticillata, Origanum vulgare subsp. glandulosum, Lavandula multifida, and Thymus
munbyanus subsp. ciliatus. The anti-MRSA activity was evaluated by the technique of agar diffusion and
determination of MICs. We also studied the kinetics of destruction of these oils against MRSA strain ATCC
43300. The four essential oils showed a good anti-MRSA activity. Oils with the highest activity are; Origanum
vulgare subsp. glandulosum, Thymus munbyanus subsp. ciliatus, Lavandula multifida and Ammoides verticillata
respectively. The kinetics of destruction of all essential oils against MRSA ATCC 43300 strain is dependent on
concentration. The Concentration 1% allows a total destruction; while the concentration 0.5% was bactericidal
only with Origanum vulgare, whereas the concentration 0.25% and 0.125% have had a low destruction
respectively. We concluded that the essential oils can be used as an anti-MRSA.
