dc.description.abstractPlasmodium falciparum has successfully developed resistance to almost allcurrently used antimalarials. A single nucleotide polymorphism in the P. falciparum chloroquine resistance transporter (Pfcrt) gene at position 76 resulting in a change in coding from lysine to threonine (K76T)has been implicated to be the corner stone of chloroquine resistance. Widespread resistance to chloroquine in endemic regions led to its replacement with other antimalarials. In some areas this replacement resulted in a reversion of the mutant T76 allele to the wild-typeK76 allele. This study was conducted to determine the prevalence of the K76T mutation of the Pfcrtgene eight years after the ban on chloroquine sales and use. A cross-sectional study was conducted in 6 regional hospitals in Ghana.PCR-RFLP was used to analyze samples collected to determine the prevalence ofPfcrtK76T mutation. Of the 1318 participants recruited for this study, 246 were found to harbour the P. falciparum parasites, of which 60.98% (150/246) showed symptoms for malaria. The prevalence of the PfcrtT76 mutant allele was 58.54% (144/246) and that of the K76 wild-type allele was 41.46% (102/246).No difference of statistical significance was observed in the distribution of the alleles in the symptomatic and asymptomatic participants (P = 0.632).No significant association was, again, observed between the alleles and parasite density (P = 0.314),as well as between the alleles and Hb levels of the participants (P = 0.254).Notwithstanding the decline in the prevalence of the PfcrtT76 mutation since the antimalarialpolicy change in 2004,the 58.54% prevalence recorded in this study is considered high after eight years of the abolishment of chloroquine usage in Ghana. This is in contrast to findings from other endemic areas where the mutant allele significantly reduced in the population after a reduction chloroquine useen_US
