Rapid determination of antiviral drug susceptibility of human cytomegalovirus by real-time PCR

Résumé

A quantitative real-time PCR-based assay was developed for determination of cytomegalovirus (HCMV) susceptibility to antiviral drugs. After HCMV isolate-growth for 4 days, antiviral drug susceptibility was determined by measuring the reduction of intracellular HCMV DNA in the presence of increasing concentrations of either ganciclovir, or foscarnet or cidofovir. The 50% inhibitory concentration (IC(50)) was the drug concentration that reduced the number of HCMV genome copies by 50%. The IC(50) values were measured for seven HCMV reference strains sensitive or resistant to one or more antiviral drugs. The antiviral susceptibility of 21 HCMV isolates was then tested and the results were consistent with prior determination of their phenotype and/or genotype by plaque reduction assay and sequencing. The real-time PCR susceptibility assay reported here was found to be highly reproducible, simpler to perform than the plaque reduction assay, and amenable to use in the routine diagnostic virology laboratory.
