Abstract
This article aimed to analyze the antibacterial activity of green propolis extract on the bacteria Staphylococcus aureus and Streptococcus pyogenes, both causing airway infections. Bacteria were seeded on plates containing filter paper discs. For each species 12 plates were used, divided into 3 groups. In the first group, the paper discs were soaked in 1 ml of pure propolis extract. In the second group, the discs were soaked in 1 ml of 10% propolis alcohol extract and in the third group, 1 ml of 70% alcohol was added to the discs. Inhibition halos were measured, and the results showed greater antimicrobial action of the extract in Staphylococcus aureus, but the growth of Streptococcus pyogenes was also impaired, complementing scientific evidence that green propolis extract has potential for use in therapeutic approaches involving the fight against pathogenic bacteria.
