Effects of peptides on membrane permeability expressed as the per cent of fluorescent mature sporozoites (mean ± standard deviation, n = 9). Letters indicate those results not significantly different from each other at the p < 0.05 level. Positive control group (+): digitonin/PBS; negative control group (−): PBS. The most active peptides were 1, 5 and 6 that presented 94, 89 and 94 % antiplasmodial activity, respectively
