Atividade antimicrobiana do extrato de própolis frente a isolados de Staphylococcus coagulase positiva e Malassezia pachydermatis de otite canina

Abstract

The purpose of this study was to evaluate the antimicrobial potential of the propolis extract, natural substance known for its therapeutic properties, against to 67 microbial isolates of canine otitis. The Minimum Bactericidal Concentration (MBC) of the propolis extract against the isolates of coagulase-positive Staphylococcus and the Minimum Fungicide Concentration (CFM) for Malassezia sp. isolates were determined using the broth microdilution technique. The MBC was 15.1mg mL-1, while the MFC was 2.4mg mL-1. Thus was shown the antimicrobial potential of the propolis extract tested against these two agents and the lower bactericidal and fungicidal concentration needed for the inhibition of them.
