The inhibition the Tet(K) efflux pump of tetracycline resistant Staphylococcus epidermidis by essential oils from three Salvia species.

Unlabelled: The inhibition of efflux pumps is an attractive and powerful response to the emergence of bacteria resistant to antibiotics. Essential oils (EOs) from Salvia fruticosa, Salvia officinalis and Salvia sclarea reduce the minimal inhibition concentration of tetracycline, decrease efflux of antibiotic and decrease the expression of tet(K) gene in tetracycline resistant clinical isolates of Staphylococcus epidermidis. In all the cases S.
