Cultivation of fertile Plasmodium falciparum gametocytes in semi-automated systems. 1. Static cultures.

Abstract:

:A semi-automated cultivation apparatus for the in vitro culture of Plasmodium falciparum gametocytes is described. This apparatus has been designed to produce large numbers of fertile sexual stages for use in the development of a gamete vaccine or for the infection of suitable mosquitoes. These mosquitoes in turn may be used for the development of a possible sporozoite vaccine. Loss of red cells during medium change has been eliminated and the addition of warmed fresh medium simplified compared to similar systems described previously. Material harvested from this apparatus has been used for infecting mosquitoes. Up to 98% of Anopheles stephensi were infected with a mean oocyst count of 24 per positive gut (range one to 109). The importance of satisfactory presentation of gametocytes for mosquito infection is stressed. The possible presence of substances in normal human sera which inhibits exflagellation to a variable degree and reduces mosquito infectivity is also discussed.
