Effects of various concentrations of drugs on Plasmodium falciparum oocyst density. A) Effects of different Sulfadoxine concentrations on oocyst distributions in mosquitoes. B) Effects of different Pyrimethamine concentrations on oocyst distributions in mosquitoes. C) Effects of different Sulfadoxine462 pyrimethamine concentrations on oocyst distributions in mosquitoes. S, sulfadoxine; P, pyrimethamine; SP, sulfadoxine-pyrimethamine; SD3 = sulfadoxine concentration equivalent to serum levels of sulfadoxine at day 3 following an oral dose of sulfadoxine-pyrimethamine; SD7, sulfadoxine concentration equivalent to serum levels of sulfadoxine at day 7 following an oral dose of sulfadoxine466 pyrimethamine; SD14, sulfadoxine concentration equivalent to serum levels of sulfadoxine at day 14 following an oral dose of sulfadoxine-pyrimethamine; idem for PD3, PD7, PD14, SPD3, SPD7 and SPD14.
