Concentration and purification by magnetic separation of the erythrocytic stages of all human Plasmodium species

Abstract

Background : Parasite concentration methods facilitate molecular, biochemical and immunologicalresearch on the erythrocytic stages of Plasmodium. In this paper, an adaptation of magnetic MACS®columns for the purification of human Plasmodium species is presented. This method was useful forthe concentration/purification of either schizonts or gametocytes. Results and conclusions : The magnetic removal of non-parasitized red blood cells (in vivo andin vitro) using magnetic columns (MACS) was evaluated. This easy-to-use technique enrichedschizonts and gametocytes from Plasmodium falciparum in vitro cultures with a very high degree ofpurity. In addition, all haemozoin-containing stages (schizonts and/or gametocytes) from theperipheral blood of infected patients could be concentrated using this method. This method isparticularly useful for the concentration of non-falciparum species, which do not grow in cultureand are otherwise difficult to obtain in large amounts.
