Resumo: Introduction: bovine mastitis is a major problem in dairy production, mainly caused by Gram-positive bacteria. The search for active ingredients that act upon these microorganisms is growing due to occurrence of bacterial multiresistance. Objectives: to assess the minimum bactericidal concentration (MBC) of Origanum vulgare L. (oregano) essential oil against bacteria isolated from mastitic milk. Methods: the antimicrobial activity of O. vulgare essential oil was measured against 71 bacteria from the genera Streptococcus, Staphylococcus and Corynebacterium isolated from the bovine milk and against three pattern strains, that is, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. The technique was dilution in microplate. Results: the mean minimal bactericidal concentration (MBC) ranged from 0.23 % to 2 % against the bacteria isolated from bovine milk, with the lowest concentration for Streptococcus genus and the highest for coagulase-negative Staphylococcus. Regarding the pattern strains, the MBC was 3.17 % and 0.35 % for S. aureus and Escherichia coli respectively and showed no effect for Pseudomonas aeruginosa. Conclusions: the results confirmed the in vitro activity of Origanum vulgare L. oil against the bovine mastitis-related bateria.

La búsqueda de principios activos que actúen en esos microrganismos es creciente, sobre todo por la ocurrencia de multirresistencia bacteriana. Objetivos: evaluar la concentración bactericida mínima del aceite esencial de Origanum vulgare L. (orégano) frente a bacterias aisladas de leche mastítica. Métodos: se evaluó la actividad antimicrobiana del aceite esencial de O. vulgare frente a 71 bacterias aisladas de leche bovina, de los géneros Streptococcus, Staphylococcus y Corynebacterium; y 3 cepas patrón de Pseudomonas aeruginosa, Staphylococcus aureus y Escherichia coli. La técnica utilizada fue de dilución en microplaca. Resultados: la concentración bactericida mínima media varió de 0,23 a 2 % frente a las bacterias aisladas de leche bovina, con la menor concentración para el género Streptococcus y la mayor para Staphylococcus coagulasa negativa. En cuanto a las cepas patrones la concentración bactericida mínima fue de 3,17 y 0,35 % para S. aureus y Escherichia coli, respectivamente; no presentó efecto para Pseudomonas aeruginosa. Conclusiones: en los resultados se comprobó la actividad in vitro del aceite de orégano frente a las bacterias relacionadas con la mastitis bovina.application/pdfspaRevista cubana de plantas medicinales.
