Genetic 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...
متن کاملIn vitro selection of Plasmodium falciparum drug-resistant parasite lines
The in vitro selection of antimicrobial resistance in important pathogens can provide critical information on the genetic basis of drug resistance, and such information can be used to predict, anticipate and even contain the spread of resistance in clinical practice. For instance, the discovery of the role of pfmdr1 in mefloquine resistance in malaria parasites resulted from in vitro studies. H...

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 کاملSelection and characterization of 5-fluoroorotate-resistant Plasmodium falciparum.
Previous studies have shown that 100 nM 5-fluoroorotate (5-FO) is sufficient to block the in vitro proliferation of Plasmodium falciparum without causing toxicity to mammalian cells. In anticipation of potential drug resistance, a study was undertaken to identify P. falciparum cells that would proliferate in the presence of 5-FO. About 3 x 10(6) UV-irradiated as well as nonirradiated parasites ...
