Sporozoite Rates and Densities in the Members of the Anopheles punctulatus Complex.
Abstract
Malaria sporozoite and inoculation rates were measured for 104,000 anophelines in Papua New Guinea. Comparisons of inoculation rates with parasite prevalences indicates that Plasmodium falciparum is more efficiently transmitted by sporozoites than is P. vivax. The increased efficiency of transmission may be related to the greater sporozoite densities found in P. falciparum infected mosquitoes, which were 10 fold greater than in P. vivax infected mosquitoes. Significant correlations were found between sporozoite rates and the human blood index of the vectors and between the sporozoite rate and bed net usage. No significant correlation was found between the sporozoite rate and either the demographic profiles of the different villages or with parasite prevalences found in children in the different villages. Keywords: Anopheles punctulatus.
