过去二十年中,多数有疟疾传播的国家报道恶性疟原虫对氯喹抗性,随即在许多国家又出现对其它抗疟药的抗性。本文集中说明在化学治疗方面疟原虫的抗药性。乙胺嘧啶和氯胍恶性疟对乙胺嘧啶的抗性进展迅速。首次报告见于1953年,现已广泛分布。乙胺嘧啶的抗性主要以对无性期原虫的作用衡量,然而现在已有红细胞前期产生抗性的报告。早已发现红内期原虫对氯
In the past two decades, most countries with malaria transmission reported resistance to chloroquine by Plasmodium falciparum, followed by emergence of resistance to other antimalarial drugs in many countries. This article focuses on the chemical resistance of Plasmodium. Pyrimethamine and proguanil Plasmodium falciparum on pyrimethamine resistance is progressing rapidly. The first report was found in 1953 and is now widely distributed. The resistance to pyrimethamine is mainly measured as the effect on the protozoan protozoa, however, there is now a report of resistance to erythropoiesis. Red-stage protozoa have been found on chlorine
