Reported are malaria sporozoite and inoculation rates over a 1-year period in eight epidemiologically defined villages of different endemicity in Madang Province, Papua New Guinea. In the study, more than 41 000 wild-caught mosquitos were analysed for Plasmodium falciparum and P. vivax sporozoites by ELISA. In a given village the entomological inoculation rates correlated strongly with the prevalences of both these malarial parasites in children. However, the prevalence of P. falciparum infections in children was much higher than that of P. vivax, despite similar inoculation rates for the two species. These data suggest that in Papua New Guinea P. falciparum is more efficiently transmitted than P. vivax from mosquito to man. The increased efficiency of transmission of P. falciparum may be due to the heavier sporozoite densities in wild-caught mosquitos naturally infected with P. falciparum sporozoites that were tenfold greater than the sporozoite densities in mosquitos infected with P. vivax.
报告了巴布亚新几内亚马当省八个根据流行病学定义的、疟疾流行程度不同的村庄在一年时间内的疟原虫孢子体和接种率。在该研究中，通过酶联免疫吸附测定法（ELISA）对41000多只野外捕获的蚊子进行了恶性疟原虫和间日疟原虫孢子体分析。在特定村庄，昆虫学接种率与儿童中这两种疟原虫的流行率密切相关。然而，尽管两种疟原虫的接种率相似，但儿童中恶性疟原虫感染的流行率远高于间日疟原虫。这些数据表明，在巴布亚新几内亚，恶性疟原虫从蚊子传播到人的效率高于间日疟原虫。恶性疟原虫传播效率的提高可能是由于自然感染恶性疟原虫孢子体的野外捕获蚊子中孢子体密度更高，其比感染间日疟原虫的蚊子中的孢子体密度高十倍。
