    Drug-resistant P. falciparum. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. However, direct proof of a causal relationship has remained elusive and most models have posited a multigenic basis of resistance. Although chloroquine is an antimalarial, it is often not sufficient for prophylaxis. Chloroquine used to be the antimalarial of choice and it was widely used for from 1947 onwards. As a result, the malaria parasites endemic to certain regions developed a resistance to chloroquine. Resistance to chloroquine was observed as early as the 1950s.

    Quinine comes from the bark of a tree native to South America. As the threat of antimalarial drug resistance grows, there is increasing pressure to sustain the efficacy of existing treatments, develop alternative treatments, as well putting in place preventative measures such as bednets.

  6. 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.

    Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Following the war, chloroquine and DDT emerged as the two principal weapons in WHO’s global eradication malaria campaign. Subsequently, chloroquine resistant P. falciparum probably arose in four separate locations starting with the Thai-Cambodian border around 1957; in Venezuela and parts of Colombia around 1960; Chloroquine is only effective against malaria from certain areas of the world. chloroquine may worsen psoriasis, seizures, hearing problems, and liver conditions.
