We examined the antibacterial activities of several types of propolis, including Africanized honey bee green propolis and propolis produced by meliponini bees. The antibacterial activity of green propolis against Micrococcus luteus and Staphylococcus aureus was superior to that of Melipona quadrifasciata and Scaptotrigona sp propolis. Only two samples of propolis (green propolis and Scaptotrigona sp propolis) were efficient against Escherichia coli.
