ABSTRACT Surveillance of Plasmodium falciparum crt(K76T) [Pfcrt(K76T)], a resistance marker of chloroquine and, limitedly, amodiaquine, in >4,000 children in northern Ghana revealed a prevalence of 79%. Pfcrt(K76T) was heterogeneously distributed and associated with chloroquine use, low parasitemia, and the dry season. Widespread chloroquine resistance challenges the regional life span of amodiaquine as a partner drug in artemisinin combination therapy.

ABSTRACTDihydroartemisinin-piperaquine is the current frontline artemisinin combination therapy (ACT) forPlasmodium falciparummalaria in Cambodia but is now failing in several western provinces. To investigate artesunate plus mefloquine (AS+MQ) as a replacement ACT, we measured the prevalence of multiplepfmdr1copies—a molecular marker for MQ resistance—in 844P. falciparumclinical isolates collected in 2008 to 2013. Thepfmdr1copy number is decreasing in Western Cambodia, suggesting thatP. falciparumis regainingin vitrosusceptibility to MQ.
