Fig. 4From: Methylene blue induced morphological deformations in Plasmodium falciparum gametocytes: implications for transmission-blockinga Untreated P. falciparum gametocytes. b Primaquine treated gametocytes. Untreated gametocytes display normal morphology with intact chromatin and cytoplasm. Gametocytes treated with as high as 25 µM primaquine also display normal morphology without any morphological aberrations, hence demonstrating absence of any significant in vitro gametocytocidal effect of primaquineBack to article page
