    Key words chloroquine, resistance, genetic markers, Pfcrt, Pfmdr, mutations. Introduction The problem of chloroquine resistance in Plasmodium falciparum infections has complicated the management of malaria in countries where chloroquine is the first line antimalarial drug. The effect is felt mostly in the malaria endemic countries 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. Resistance developed by most parasites that were initially sensitive to drugs mostly result from mutations in the genes responsive to the drug. Mutations in the Plasmodium falciparum chloroquine resistance transporter, PfCRT, are the major determinant of chloroquine resistance in this lethal human malaria parasite. Here, we describe P.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  3. Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of Plasmodium falciparum not being cured by administration of chloroquine being reported in the 1950s.

    Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. Whether the protein mediates extrusion of the drug acting as a channel or as a carrier and which is the protonation state of its chloroquine substrate is the subject of a. Update Chloroquine-Resistant Plasmodium falciparum -- Africa. The first confirmed cases of chloroquine-resistant Plasmodium falciparum acquired in Africa were reported in 1978 1 and occurred in non-immune travelers who had been in East Africa for relatively short periods of time. Background Mutations in the chloroquine resistance transporter PfCRT change the susceptibility of Plasmodium falciparum to diverse antimalarial drugs. Results In addition to chloroquine, PfCRT transports quinine, quinidine, and verapamil, which bind to distinct but antagonistically interacting sites.
