Genotyping for point mutations in selected codons of pfcrt and pfmdr-1 genes of Plasmodium falciparum among patients with uncomplicated malaria in Mbita district Kenya

Abstract

Malaria remains a leading cause of morbidity and mortality in Kenya, especially in young children and pregnant women. Due to widespread resistance of Plasmodium falciparum to drugs such as Chloroquine (CQ) and Sulfurdoxine-Pyrthamine (SP), Artemisisnin Combination Therapy (ACT) was adopted in Africa as a means of improving treatment efficacy and slowing the spread of resistance. The development of drug resistance by the parasites for the various malaria drug regimens that have been in use before has been attributed to point mutations within the parasite genome. Therefore this study investigated the prevalence of point mutations in selected codons of the pfcrt and pfmdr-1 genes of Plasmodium falciparum. It is however unclear whether ACT will be effective in preventing the selection of resistant parasites in Africa, where parasite transmission rates are generally much higher with parts of Asia and Africa already reporting a reduction in sensitivity to ACT.
