Data on selected antimalarial drug resistance markers in Zambia.

ABSTRACT

This article describes data on selected resistance markers for antimalarial drugs used in Zambia. Antimalarial drug resistance has hindered the progress in the control and elimination of malaria. Blood samples were collected during a cross-sectional household survey, conducted during the peak malaria transmission, April to May of 2017. Dried blood spots were collected during the survey and transported to a laboratory for analysis. The analysed included polymerase chain reaction (PCR) followed by high resolution melt (HRM) for mutations associated with Sulfadoxine-pyrimethamine resistance in the Plasmodium falciparum dihydrofolate reductase (Pfdhfr) and P. falciparum dihydropteroate synthase (Pfdhps) genes. Mutations associated with artemether-lumefantrine resistance in falciparum multi-drug resistance gene 1 (Pfmdr1) were also assessed using PCR and HRM analysis, whereas the P. falciparum Kelch 13 (PfK13) gene was assessed using nested PCR followed by amplicon sequencing.
