We designed primers and cycling probes to detect the tandem repeat (TR) of cyp51A promoter in Aspergillus fumigatus. A control-probe was designed to anneal to the outside of the TR region, whereas a TR-probe was designed to anneal to the inside of the TR region. For amplification and probe-hydrolysis detection, the CycleavePCR system was used. Although the difference between Ct values of the wild-type genome for the control-probe and the TR-probe was around -0.1, the difference between Ct values of TR-harboring strains was around 0.7. These data indicate that this is a simple method to detect TR in azole-resistant A. fumigatus.
