Abstract: High-throughput drug screening methods against the intracellular stage of Leishmania have been facilitated by the development of in vitro models of infection. The use of cell lines rather than primary cells facilitates these methods. Peripheral blood mononuclear cell (PBMC) derived macrophages and THP-1 cells were infected with stationary phase egfp transfected Leishmania amazonensis parasites and then treated with anti-leishmanial compounds. Drug activity was measured using a flow cytometric approach, and toxicity was assessed using either the MTT assay or trypan blue dye exclusion. Calculated EC50’s for amphotericin B, sodium stibogluconate, and miltefosine were 0.1445 ± 0.0005 μg/ml, 0.1203 ± 0.018 mg/ml, and 26.71 μM using THP-1 cells, and 0.179 ± 0.035 μg/ml, 0.1948 ± 0.0364 mg/ml, and 13.77 ± 10.74 μM using PBMC derived macrophages, respectively. We conclude that a flow cytometric approach using egfp transfected Leishmania species can be used to evaluate anti-leishmanial compounds against the amastigote stage of the parasite in THP-1 cells with excellent concordance to human PBMC derived macrophages.
