Malaria parasite. Coloured transmission electron micrograph (TEM) of a sexual male malaria microgametocyte in a mosquito (Anopheles sp.) gut. The microgametocyte (Plasmodium sp.) releases male microgametes (green/pink, one at top right) after it is ingested by a mosquito feeding on an infected human. Each motile microgamete possesses a flagellum built from fibrils (pink, paired) assembled near the gametocyte membrane. The gametes fertilise the female macrogametocytes (not seen). Asexual reproduction then produces the stage that infects humans. Magnification: x14,300 at 6x7cm size.
