RESISTANCE 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 کاملinduction of drug resistance in plasmodium falciparum: an intermittent drug exposure method
the production of experimentally induced drug resistance in the laboratory provides valuable opportunities for investigators to study the nature and genetics of drug resistance mechanisms to a given agent, patterns of cross resistance and the mode of action of drugs. at the beginning the continuous drug exposure was chosen as a standard procedure to produce drug— resistant strains of p. falcipa...
متن کاملVariations in frequencies of drug resistance in Plasmodium falciparum.
Continual exposure of malarial parasite populations to different drugs may have selected not only for resistance to individual drugs but also for genetic traits that favor initiation of resistance to novel unrelated antimalarials. To test this hypothesis, different Plasmodium falciparum clones having varying numbers of preexisting resistance mechanisms were treated with two new antimalarial age...
متن کاملWithin-host competition and drug resistance in the human malaria parasite Plasmodium falciparum.
Infections with the malaria parasite Plasmodium falciparum typically comprise multiple strains, especially in high-transmission areas where infectious mosquito bites occur frequently. However, little is known about the dynamics of mixed-strain infections, particularly whether strains sharing a host compete or grow independently. Competition between drug-sensitive and drug-resistant strains, if ...
متن کاملGenetic alteration in drug resistance markers of Plasmodium falciparum.
Plasmodium falciparum shows plasticity in its genome. For its survival it can delete certain genes (or portions) if not needed for its growth and has the capability to regulate its genes under various stages of its life cycle as well as under unfavourable environmental conditions. Parasite shows enormous amount of antigenic variation under immune pressure leading to the emergence of vaccine res...
