Progress of researches on genes associated with sulfadoxine-pyrimethamine resistance in Plasmodium vivax / 中国血吸虫病防治杂志

ABSTRACT

Malaria is a parasitic disease which threatens human life and health seriously. Sulfadoxine-pyrimethamine (SP) has been recommended for intermittent preventive treatment of malaria in children and pregnant women, and also used as a compound component of artemisinin based therapy. The mechanisms of SP resistance in P. falciparum involve point mutations in the genes encoding dihydrofolate reductase (DHFR) and dihydropteroate synthase (DHPS), and the drug pressure can also lead to the mutations in the two genes of P. vivax. To provide the information for the formulation of anti-malarial strategies, this article reviews the discovery, application, effect of SP, and the resistance mechanism and research progress of the related genes in P. vivax.
