Genetic mapping of the chloroquine-resistance locus on Plasmodium falciparum chromosome 7.
The resurgence of malaria in recent decades has been accompanied by the worldwide spread of resistance to chloroquine, a drug once uncontested as the first-line antimalarial agent because of its efficacy and low toxicity. Chloroquine-resistant strains of Plasmodium falciparum counter the drug by expelling it rapidly via an unknown mechanism. In the absence of explicit biochemical knowledge of t...
متن کاملRESISTANCE OF PLASMODIUM FALCIPARUM TO CHLOROQUINE IN SOUTH EASTERN IRAN
In vivo and in vitro assessments of the response of P. falciparum to chloroquine using WHO standard kits and techniques were carried out in I ran Shahr, Sistan and Baluchestan province of Iran in 1985. In the in vivo assessment, 24 malaria patients treated with chloroquine (25mg/kg over three days) were followed up for one to four weeks. The mean parasite clearance time was 4.3 days and in...
متن کاملOn the Mechanism of Chloroquine Resistance in Plasmodium falciparum
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 scienti...
متن کاملOptical mapping of Plasmodium falciparum chromosome 2.
Detailed restriction maps of microbial genomes are a valuable resource in genome sequencing studies but are toilsome to construct by contig construction of maps derived from cloned DNA. Analysis of genomic DNA enables large stretches of the genome to be mapped and circumvents library construction and associated cloning artifacts. We used pulsed-field gel electrophoresis purified Plasmodium falc...
متن کاملPlasmodium falciparum chloroquine-resistance transporter gene detection in imported Plasmodium falciparum malaria cases.
To the Editor—We share the cogent sentiments expressed by Farcas et al. [1] about the great interest of PCR-based methods for the diagnosis of imported malaria, given that, in most westernized countries, morbidity and death due to this protozoan infection among returned travelers is on the rise [2]. Because we have tested 1900 patients per year since Octo-ber 1999, we have accumulated a large a...
