The IDI-VanR® Assay is a qualitative in vitro test for the rapid detection of vancomycinresistance (vanA and vanB) genes directly from rectal swabs. The IDI-vanR® Assay detects the presence of the vanA and vanB genes that can be associated with vancomycin-resistant enterococci (VRE). The assay is performed on an automated realtime PCR instrument with rectal swabs from patients at risk for VRE colonization. The IDI-VanR® Assay can be used as an aid to identify, prevent and control vancomycinresistant colonization in healthcare settings. Concomitant cultures are necessary to recover organisms for epidemiological typing, susceptibility testing and for further confirmatory identification. The IDI-VanR® Assay is not intended to diagnose VRE infections nor to guide or monitor treatment for VRE infections.

Following specimen lysis, amplification of the vanA and vanB targets occurs. Amplification of the IC, a DNA fragment of 294-bp including a 254-bp sequence not found in VRE, will also take place unless there are PCR inhibitory substances. The amplified DNA targets are detected with molecular beacons, a hairpin-forming single-stranded oligonucleotides labelled at one end with a quencher and at the other end with a fluorescent reporter dye (fluorophore). In the absence of target, the fluorescence is quenched. In the presence of target, the hairpin structure opens upon beacon/target hybridization, resulting in emission of fluorescence. For the detection of vanA amplicons, the molecular beacon contains the fluorophore FAM at the 5' end and the non-fluorescent quencher moiety DABCYL at the opposite end of the oligonucleotide. For the detection of the vanB amplicons, the molecular beacon contains the fluorophore Texas Red at the 5' end and the quencher DABCYL at the 3' end. For the detection of the Internal Control (IC) amplicons, the molecular beacon contains the fluorophore TET at the 5' end and the quencher DABCYL at the 3' end. Each beacon-target hybrid fluoresces at a wavelength characteristic of the fluorophore used in the particular molecular beacon. The amount of fluorescence at any given cycle, or following cycling, depends on the amount of specific amplicons present at that time. The SmartCycler® software simultaneously monitors the fluorescence emitted by each beacon, interprets all data, and provides a final result at the end of the cycling program.
