Viability of L. (V) braziliensis promastigotes in response to each type of propolis extract. Parasites were incubated for 96 h with dry, alcoholic, and glycolic propolis extract at (a and d) 10 μg/mL, (b and e) 50 μg/mL, or (c and f) 100 μg/mL. Bars represent means ± SD of two representative experiments performed in quadruplicate. AUC accounts for Area under the Curve and it corresponds to the area of the geometric figure made by the concentration curve of a drug as a function of time. The Kruskal–Wallis nonparametric test, followed by Dunn's posttest, was used to compare among experimental groups (^∗p < 0.05, ^∗∗p < 0.01, and, posttest for linear trend, p < 0.0001).
