High prevalence of drug-resistance mutations in Plasmodium falciparumand Plasmodium vivaxin southern Ethiopia

ABSTRACT

Background: In Ethiopia; malaria is caused by both Plasmodium falciparum and Plasmodium vivax. Drug resistance of P. falciparum to sulfadoxine-pyrimethamine (SP) and chloroquine (CQ) is frequent and intense in some areas. Methods: In 100 patients with uncomplicated malaria from Dilla; southern Ethiopia; P. falciparum dhfr and dhps mutations as well as P. vivax dhfr polymorphisms associated with resistance to SP and P. falciparum pfcrt and pfmdr1 mutations conferring CQ resistance were assessed. Results: P. falciparum and P. vivax were observed in 69
