qPCR analysis. The transcriptional expression of CDR1, CDR2 and MDR1 in the tested C. albicans or C. tropicalis
isolates was measured using qPCR as previously reported. The primers used are shown in Supplementary
Results Table S6. 18S rRNA served as the internal control in C. albicans, while ACT1 was used as an internal control
in C. tropicalis. The transcript levels of the detected genes were calculated using the formula 2−ΔΔCT.
