Antimicrobial Effect in Vitro of Argentineans Colombians and Cuban Propolis On Streptococcus Mutans Atcc 25175
The highest effect bacteriostatic was presented by the sample 2 (propolis from Colombia) after 24 hours of incubation. 70% of the propóleo samples increased their activity after a time of incubation of 48 hours compare to the effect shown to the 24 hours. All the Colombian samples showed a superior effect, when the bacteria were exposed to the propóleo for a longer period of time; in two of these cases until of five dilutions, samples 2 and 3, this effect was presented in a moderate way, using the argentine samples 6 and 10 while the other samples (30%) remained steady.
