Abstract

This work was carried through with the objective to evaluate the effect in vitro of essential oils in the inhibition of Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 25923. We tested the essential oils of rosemary (Rosmarinus officinalis), marjoran (Origanum marjorana L.), basil (Ocimum basilicum L.), eucalyptus (Eucalyptus citriodora), citronela (Cymbopogon nardus), grass-lemon (Cymbopogon citratus), previously extracted for the technique of drag the vapor. The oils had been submitted at 10 different dilutions (1/9, 2/8, 3/7, 4/6, 5/5, 6/4, 7/3, 8/2, 1/9, 1). The used technique was the embodiment of the samples in barren absorbent records that had been added on agar to contain the microorganisms and reading to subsequent of inhibition halos. The results had demonstrated that all the essential oils in the tested concentrations had not presented innibitory characteristics front to the Escherichia aureus coli ATCC 25922 and Staphylococcus aureus ATCC 25923.
