Rapid detection of a molecular marker for chloroquine-resistant falciparum malaria

Antimicrob Agents Chemother. 2002 Aug;46(8):2684-6. doi: 10.1128/AAC.46.8.2684-2686.2002.

Abstract

A PCR-based technique using molecular beacons was developed to detect the chloroquine resistance-associated pfcrt K76T point mutation in Plasmodium falciparum. One hundred thirty African clinical isolates were tested by the new method in comparison with the PCR-restriction fragment length polymorphism method. This rapid and inexpensive genomic assay could expand the possibilities for monitoring chloroquine resistance.
