THE BIOLOGY OF PLASMODIUM-FALCIPARUM TRANSMISSION STAGES

The most important function of any parasite is to secure transmission to new hosts. The gametocyte, the stage which has become developmental ly committed to the sexual cycle, provides a critical link in the tran smission of Plasmodium falciparum from the human host to the anophelin e mosquito vector. It is therefore imperative that our determination t o understand the biology of the gametocyte is greater than the technic al obstacles which have resulted in the gametocyte being left very muc h out of the limelight by the intensive investigation of the asexual b loodstream parasite. Here we explore the areas of gametocyte biology w hich by nature of their relevance to control and pathology as well as basic biology, are the subjects of investigation in our laboratory. We also point out areas in need of particular attention.
