Use of a Locked-Nucleic-Acid Oligomer in the Clamped-Probe Assay for Detection of a Minority Pfcrt K76T Mutant Population of Plasmodium falciparum

摘要

Given the emergence of drug resistance and the high rate of polyclonal microorganism infections, the availability of a fast and sensitive test to detect minority mutant populations would be an improvement in the diagnosis of infectious diseases. A clamped-probe real-time PCR assay to diagnose the Plasmodium falciparum K76T mutation in clone populations was developed, using a wild-type-specific locked-nucleic-acid-containing oligomer to suppress wild-type PCR amplification and to enhance melting analysis with a mutation-specific detection probe.
