  • Gametocyte

    The sexual stage of malaria parasites. Male gametocytes (microgametocytes) and female gametocytes (macrogametocytes) are inside red blood cells in the circulation. If they are ingested by a female Anopheles mosquito, they undergo sexual reproduction which starts the extrinsic (sporogonic) cycle of the parasite in the mosquito. Gametocytes of Plasmodium falciparum are typically banana or crescent-shaped (from the latin falcis=sickle). 1
