Fidock Chloroquine Resistance in Plasmodium falciparum - microbewiki https://microbewiki.kenyon.edu/index.php/ Development of Chloroquine Resistance in Plasmodium falciparum Drug resistance is the ability of a parasite to survive despite the presence of a drug that is meant to kill it in toxic levels. falciparum strains and did not differ between chloroquine-resistant and -sensitive parasites In 2006, the Senegalese National Malaria Control Programme recommended artemisinin-based combination therapy (ACT) with artemether–lumefantrine as the first-line treatment for uncomplicated Plasmodium falciparum malaria. In some places it is chloroquine-resistant. To monitor drug resistance in Plasmodium vivax, a multidrug resistance 1 (Pvmdr1) gene and a putative transporter protein (Pvcrt-o) gene were used ….
