Comparing Plasmodium falciparum 3D7 and FCB2 strains’ oocyst morphological characteristics. Female mosquito midguts infected with FCB2 gametocytes obtained from parasite culture at 0.3% parasitaemia were analysed by 0.5% mercurochrome staining. A, B 3D7 oocysts on day 12 post-infection; C, D FCB2 oocysts on day 12 post-infection. Black arrows indicate viable oocysts; blue arrows show atrophic oocysts. All oocysts visualized at 40X on a Primo Star Carl Zeiss microscope
