In vivo time-dependent reduction in Leishmania tropica load following treatment with miltefosine (ML) and moxidectin (MOX) using Galleria mellonella as the infection model. Statistical analysis of the area under the curve (AUC) revealed significant differences between all groups (p < 0.05; one-way ANOVA with Tukey’s HSD test). Groups with different letters are significantly different: PIL (a) 57.37 (SE = 0.19); PIL treated with ML (b) 25.60 (SE = 0.30); PIL treated with MOX (c) 19.32 (SE = 0.24).
