Abstract：
:In vitro gametocytogenesis of Plasmodium falciparum was observed in all 22 isolates established in this laboratory. Gametocytes were produced in variable numbers--up to 3% of red cells--for a limited period of time after which this stage was seen only very sporadically. Complete maturation of microgametocytes in vitro was obtained in all 14 of the isolates that were tested for exflagellation. Up to 88.2% of membrane-fed Anopheles stephensi were infected from material produced in culture. It was also possible to infect A. gambiae and A. freeborni. Addition of fresh red cells and serum to culture material promoted infectivity of gametocytes. Gametocyte infectivity declined rapidly with time in the membrane feeders held at 38 degrees C.
