Resum

Bovine mastitis is a disease with far-reaching consequences for the dairy industry.
Staphylococcus aureus is a pathogen that is especially resistant to antibiotics. The objective of this study
was to evaluate the antimicrobial activity of the essential oils Lippia citriodora (Lam.), Thymus vulgaris
(L), and a mixture of the essential oils Lippia citriodora and Thymus vulgaris (50/50 v/v), against isolates
of oxacillin-resistant Staphylococcus aureus (n=15) of positive cases of bovine mastitis. For the statistical
analysis, the IBM SPSS statistical package was used. The mixture of essential oils (Lippia citriodora and
Thymus vulgaris (50/50 v/v)) obtained the most significant antimicrobial activity in relation to pure
essential oils. It is therefore concluded that the mixture of these oils boosts their antimicrobial activity
(p<0.05). The minimum inhibitory and bactericidal concentration of this mixture for the total isolations
was 12 µL/L and 25 µL/mL, respectively.
