Background: The widespread of chloroquine-resistant Plasmodium falciparum malaria in Kenya lead to the official withdrawal of chloroquine (CQ) drug by the Government as a first-line treatment of uncomplicated P. falciparum malaria in 1999. This study aimed to investigate CQ resistant in Kenya after its withdrawal. Methods: Blood samples were collected on 3M Whatman from patients infected with P. falciparum from Chulaimbo Sub-District Hospital. DNA was extracted using Chelex method for Polymerase chain reaction (PCR) amplification of pfcrt and pfmdr-1 genes. PCR--restrictive fragment length polymorphism was performed using enzymes Apol1 and Afl3 targeting point mutation of K76T and N86Y in pfcrt and pfmdr-1 respectively. The PCR products were sequenced, genotype.. Read More»
