Abstract
Separation and concentration of parasitized erythrocytes from infected blood was achieved by centrifugation of a sample placed in a layer on top of a cushion of a Ficoll solution with a critical density. Pure suspensions of parasitized erythrocytes were obtained from Plasmodium berghei infected rodent [mide, rats, hamsters, gerbils] blood, whereas results with P. vivax infected monkey (Aotus trivirgatus) blood were partially successful. Titration experiments revealed that the parasitized erythrocytes obtained by Ficoll fractionation were infective.
