Veterinary Microbiology, Article in Press

The aims of this study were to evaluate the antimicrobial potential of propolis extract by determining the minimum bactericidal concentration (MBC) for coagulase-positive Staphylococcus isolates (Staphylococcus aureus and Staphylococcus intermedius) and the minimum fungicidal concentration (MFC) for Malassezia pachydermatis isolates.

The microorganisms were assayed using broth microdilution techniques. The MBC(90) was 21mgmL(-1), and the MFC(90) was 5.3mgmL(-1).

The propolis extract was found to exhibit antimicrobial activity against both pathogens.
