Despite the increasing number of studies that have highlighted the antibacterial activity of essential oils against many bacterial species, the mechanisms implicated in this action are still not fully understood. Understanding the mode of antibacterial activity is of great interest for their application in food and pharmaceutical industries. Staphylococcus aureus and Pseudomonas aeruginosa are associated with nosocomial and community infections. This paper is a synthesis of our works on the functional and ultrastructural damages induced in two reference strains ( Ps. aeruginosa ATCC 27853 and S. aureus ATCC 29213) treated by oregano and cinnamon essential oils. The results are compared to other publications concerning the mode of antibacterial activity of essential oils.
