IC₅₀ of the different reference drugs and infectivity percentage in Leishmania major promastigotes isolated from human and rodent.

	L. major Reference Isolates
	PGLC	32-1	32-2	32-3
Sb(III) µg/mL	4.71 ± 0.5	5.47 ± 0.34	3.62 ± 1.04	6.09 ± 0.16
Miltefosine µM	9.93 ± 3.7	12.26 ± 2.19	10.29 ± 0.03	13.24 ± 1.39

IC₅₀ of Sb(III) and miltefosine. Human isolate: PGLC, rodent isolates: 32-1, 32-2, 32-3. Infectivity percentages were calculated according to infected cells and non-infected cells. The means ± were determined from three independent experiments for the MTT assay and two independent experiments for parasite infectivity.
