Abstract: Treatments for bovine mastitis based on antibiotictherapy are not always effective which may lead to faults in recovery of diseased animals, selection of resistant bacteria and the presence of antimicrobial residues in milk. In this context the use of essential oils configures as an alternative to control mastitis pathogens in dairy cows because they have antibacterial action against gram-positive and gram-negative bacteria and no diverse effects on human health. The objective of this study was to determine, by the method of broth microdilution, the minimum inhibitory concentration (MIC) of essential oils of Salvia scl area, Eugenia caryophyllata, Thymus vulgaris, Cymbo pogon winterianus, Elettaria cardamomun, Cymbopogon flexuosus, Rosmarinus officinalis and Cinnamomum cassia for isolates of Staphylococcus aureus and Streptococcus agalactiae associated with clinical and subclinica l mastitis. C. cassia, T. vulgaris, C. flexuosus, E. caryophyllata , C. winterianus essential oils presented high anti bacterial action against both the pathogens. The S. sclarea and R. o fficinalis oils did not show significant antibacter ial activity against both the microorganisms. High synergism in antimicrobial action against S. aureus and S. agalactiae was observed in the combination of C. cassia, C. flexuosus and E. caryophyllata essential oils. Moderate synergism in antimicrobial effect was also observed in associations involving the C. cassia essential oil. The results indicated the prospect of using essential oils to control bovine mastitis caused by S. aureus and S. agalactiae.
