Abstract

The widespread of drug resistant Plasmodium falciparum has led to a rise in malaria- associated mortality most especially in sub-Saharan Africa. Falciparum malaria was confirmed by microscopic examination of Giemsa-stained blood samples of patients who presented with fever in selected State Hospitals in Ogun State, Southwestern Nigeria. Molecular methods were employed to detect the markers of resistance of P. falciparum to Chloroquine, sulphadoxine/pyrimethamine,and artesunate in Ogun State, Southwestern Nigeria. DNA was extracted from patient blood using the QiaAmp DNA Blood Minikit extraction method. Nested Polymerase Chain Reaction followed by Restriction Fragment Length Polymorphisms (PCR/RFLP) were used for the detection of P. falciparum chloroquine resistance transporter (Pfcrt), P. falciparum multidrug resistance 1 (pfmdr1), P. falciparum dihydrofolate reductase (Pfdhfr), P. falciparum dihydropteroate synthase (Pfdhps) and P. falciparum sarco/endoplasmic reticulum calcium-dependent ATPase (SERCA) PfATPase6 genes. Pfcrt (K76T ) Pfmdr1 (mdr 1 ) Pfdhfr (S108N), and Pfdhps (K540E) resistant genes were detected among the isolates while resistant SERCAPfATPase6 gene which codes for artemisinin resistance was not detected in the population.
