Figure 1From: Proanthocyanidins polymeric tannin from Stryphnodendron adstringens are active against Candida albicans biofilmsEffect of fraction F2 and of subfraction F2.4 fromStryphnodendron adstringenson the biofilm formation ofCandida albicansATCC 10231. The metabolic activity of biofilm sessile cells was quantified using an XTT assay (A–D) and total biofilm biomass was quantified using a cristal violet-based assay (E–H), after growth in the presence of amphotericin B (A and E), fluconazole (B and F), F2 (C and G) or F2.4 (D and H), for 24 or 48h, at 35°C, and under agitation. The error bar represents the standard error of the mean. *p < 0.05; **p < 0.01; ***p < 0.0001 (compared to untreated biofilms, using the Dunnett’s test).Back to article page
