    Falciparum nf54 chloroquine


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    NF54HT-GFP–luc blood stage parasites grew in in vitro culture comparably to the parent NF54 strain, expressed robust levels of luciferase and were used to calculate the IC 50 values of two known drugs that target blood stage parasites – chloroquine CQ and artesunate AS. Parasites were grown in a 96-well format and treated with increasing concentrations of drug for 72 h 0–400 nm for CQ and 0–100 nm for AS. Since the first documentation of P. falciparum chloroquine resistance in the 1950s, resistant strains have appeared throughout East and West Africa, Southeast Asia, and South America. The effectiveness of chloroquine against P. falciparum has declined as resistant strains of the parasite evolved. They effectively neutralize the drug via a mechanism that drains chloroquine away from the digestive vacuole. Nov 22, 2011 P. falciparum NF54 stage V gametocytes were cultured in the presence of drug for 3 d followed by culture in the absence of drug for 3–4 d before feeding to female A. stephensi mosquitoes. Midguts of blood-fed mosquitoes were dissected 6–7 d postfeeding, and oocyst numbers were scored.

    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.

    P. falciparum strain NF54 PfNF54 was derived from a patient who had never left the Netherlands. PfNF54 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center MR4 and is sensitive to a panel of antimalarial compounds including chloroquine and pyrimethamine. Usual Adult Dose for Malaria Prophylaxis. 500 mg chloroquine phosphate 300 mg base orally on the same day each week Comments-If possible, suppressive therapy should start 2 weeks prior to exposure; if unable to start 2 weeks before exposure, an initial loading dose of 1 g chloroquine phosphate 600 mg base may be taken orally in 2 divided doses, 6 hours apart.
