Cited by: 843 Publish Year: 2001 Author: Thomas E. Resistance is conferred by mutations in the Chloroquine Resistance Transporter (PfCRT), an integral membrane protein localized to the parasite’s internal digestive vacuole Plasmodium falciparum is the Plasmodium species responsible for 85 % of the malaria cases. 3 The appearance of chloroquine-resistant strains of falciparum malaria in South America and in Southeast Asia compounds the situation.

Recent laboratory and clinical chloroquine resistant falciparum malaria studies have associated chloroquine resistance with point mutations in the gene pfcrt. Severe malaria is treated with intravenous or intramuscular quinine or, since the mid-2000s, the artemisinin derivative artesunate, which is superior to quinine in both children and adults A new study has found that malarial parasites resistant to the effects of the anti-malarial drug Artemisinin, are capable of infecting African mosquitoes, thus enhancing the possibility of spreading drug-resistant malaria to the continent These new hybrids were screened in vitro against asexual blood stages of the chloroquine‐sensitive 3D7 strain of P.
