Staphylococcus aureus is one of the most common opportunistic pathogens in humans and several animals. Some strains can form a biofilm, which is related to chronic diseases. Green Propolis are used frequently in alternative medicine. Several studies have demonstrated the chemical similarities between Green Propolis and its botanical source Baccharis dracunculifolia. This study evaluated the antibacterial profile of the hydroalcoholic extracts of Green Propolis and Baccharis dracunculifolia against S. aureus. The antibiofilm effect of the extracts was also evaluated against a reference strain of S. aureus. The Minimal Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) for each isolate were assessed. MIC and MBC values for both extracts were similar against all bacterial strains. The extracts demonstrated good performance against the biofilm of the S. aureus ATCC 25923. Green Propolis and Baccharis dracunculifolia extract antibiofilm activities were mainly on biofilm’s newly formed and consolidated moments.
