%X To investigate the quantitative distribution of #Plasmodium falciparum$ gametocytes into the vector bloodmeal, #Anopheles arabiensis$ mosquitoes were fed on 3 volunteers naturally infected with gametocytes. The content of each mosquito midgut was smeared on a microscope slide and Giemsa stained. The distribution of gametocytes ingested by mosquitoes followed a negative binomial distribution, with apparently constant overdispersion (parameter k plus or minus S.E = 3.105 plus or minus 0.392) for the 3 series. This aggregation of gametocytes in some midguts probably facilitates the conjunction of gametes and fertilization. This suggests that #P. falciparum$ gametocytes in the peripheral blood flow of infected man do not follow an independent, homogeneous pattern but show a significant aggregation. (Résumé d'auteur)
