Antimicrobial activity of propolis was studied in Streptococcus pyogenes, oral microflora and nucotoxic fungi. CAM arid PDA medium were used for fungal study and Rogosa, APT, BHI and blood for oral bacteria, using the combination of pour-plate and Szibaisky gradient plate technique. The toxic fungi were not irubited by propolis. Propolis showed bacteriostatic action on the oral microflora inoculated by pour plate technique in gradient plate, but the growth occurred also with 1,0% propolis after 72 hours incubation. Concerning S, pyogenes, only haemolysin production was inhibits on blood agar, but bactericidal action was seen when inoculated in BHI + propolis broth. Effect of propolis on S. pyogenes depended on aeration and nutrient composition, and probably both antimicrobial and pharmaco-dinamical propriety are important for the final effect on biological system.
