The in vitro cultivation of P. falciparum ookinetes, and their enrichment on Nycodenz® density gradients

Abstract

SUMMARYEmploying a simple method of growing ookinetes of Plasmodium falciparum in culture, 40% of mature gametocytes convert to macrogametes, 4% reach the retort-form ookinete stage and 0·45% become mature ookinetes. A single-step gradient centrifugation method on 12·5% Nycodenz® enriches both gametocytes and ookinetes.
