Revisiting gametocyte biology in malaria parasites

ABSTRACT Gametocytes are the only form of the malaria parasite that is transmissible to the mosquito vector. They are present at low levels in blood circulation and significant knowledge gaps exist in their biology. Recent reductions in the global malaria burden have brought the possibility of elimination and eradication, with renewed focus on malaria transmission biology as a basis for interventions. This review discusses recent insights into gametocyte biology in the major human malaria parasite, Plasmodium falciparum and related species. This review provides an update on our current understanding of the only parasite stage that can transmit malaria from man to mosquito, the gametocyte.
