Abstract Copaiba oil is a natural product used by Amazonian populations and recognized for its medicinal properties because it has significant antimicrobial activity for several pathogenic microorganisms. The present work aimed to evaluate and characterize the effect of natural oil produced by copaiba – Copaifera multijuga against multiresistant isolates of bubaline mastitis. The nitrocefin test was performed with isolates of Staphylococcus aureus from bubaline mastitis, which were 100% positive for beta-lactamase enzyme detection. Minimum Bactericidal Concentration (MBC) of 25% to 3.12% was obtained for Enterococcus faecalis and Escherichia coli and 50% and 25% for S. aureus, but Klebsiella pneumoniae and Bacillus subtilis were resistant. MBC with 12.5% and 6.25% oil were obtained for most multiresistant bubaline mastitis isolates from the states of Pernambuco, Ceará, Bahia and Alagoas. The results demonstrated the great potential of using copaiba natural oil in the treatment of buffalo mastitis.
