Molecular monitoring of the Leu-164 mutation of dihydrofolate reductase in a highly sulfadoxine/pyrimethamine-resistant area in Africa
Abstract The selection of point mutation at codon 164 (from isoleucine to leucine) of the dihydrofolate reductase (DHFR) enzyme in Plasmodium falciparum is associated with high sulfadoxine /pyrimethamine (SP) resistance. Using the yeast expression system that allows the detection of dhfr allele pres...
