First molecular genotyping of voltage gated sodium channel alleles in Culex quinquefasciatus populations in Malaysia
A nationwide investigation was performed to detect the presence of 1014 mutation(s) in voltage gated sodium channel (kdr) gene of Culex quinquefasciatus from 14 residential areas across 13 states and a federal territory in Malaysia. Molecular genotyping of kdr mutation was performed via a modified t...
