In ongoing studies on experirnental transmission of Plasmodium falciparum in the city of Yaounde gametocyte carriers are daily being identijïed among dispensa9 patients with malaria-like complaints. This species comprises 93 % of all parasitemias and because of the selection criteria most patients have it as a recent infection. 17% of all P. falciparum-positives carry detectable gametocytes with little difference between youngsters and adults. Blood of adult carriers is taken and infection of Anopheles gambiae mosquitoes is attempted by membrane feeding; the establishment of infection is judged by the presence of oocysts.
