Abstract:
Objective To evaluate the effects of propolis on the growth of S.mutans ATCC 25175(S.m),S.sobrinus 6715(S.s) and their fluoride-resistant strains(S.m-FR,S.s-FR),and the change of their glucosyltransferase(GTF).Methods S.m and S.s were induced with sodium fluoride by minimum inhibitory concentration(MIC) to induce fluoride-resistant strains(S.m-FR and S.s-FR).Fluid dilution method was used to observe the effects of different levels of propolis on growth of S.m,S.m-FR,S.s and S.s-FR.Chemistry enzyme analysis was used to detect the influence of propolis on the enzyme activity of GTF.Results MIC of propolis for S.m,S.m-FR,S.s and S.s-FR were respectively 0.39,0.78,0.20 and 0.39 g/L.MBC of propolis for them were respectively 0.78,1.56,1.56,and 1.56 g/L.GTF of S.m,S.m-FR,S.s,and S.s-FR was decreased gradually with the increase of concentration of propolis.There were significant differences among total sample groups,and each experimental group and positive control group as well(P
