The mechanisms of terbinafine resistance in a set of clinical isolates of <i>Trichophyton rubrum</i> have been studied recently. Of these isolates, TIMM20092 also showed reduced sensitivity to azoles. The azole resistance of TIMM20092 could be inhibited by milbemycin oxime, prompting us to examine the potential of <i>T. rubrum</i> to develop resistance through multidrug efflux transporters. The introduction of a <i>T. rubrum</i> cDNA library into <i>Saccharomyces cerevisiae</i> allowed the isolation of one transporter of the major facilitator superfamily (MFS) conferring resistance to azoles (TruMFS1). To identify more azole efflux pumps among 39 ABC and 170 MFS transporters present within the <i>T. rubrum</i> genome, we performed a BLASTp analysis of <i>Aspergillus fumigatus</i>, <i>Candida albicans</i>, and <i>Candida glabrata</i> on transporters that were previously shown to confer azole resistance. The identified candidates were further tested by heterologous gene expression in <i>S. cerevisiae</i> Four ABC transporters (TruMDR1, TruMDR2, TruMDR3, and TruMDR5) and a second MFS transporter (TruMFS2) proved to be able to operate as azole efflux pumps. Milbemycin oxime inhibited only TruMDR3. Expression analysis showed that both <i>TruMDR3</i> and <i>TruMDR2</i> were significantly upregulated in TIMM20092. TruMDR3 transports voriconazole (VRC) and itraconazole (ITC), while TruMDR2 transports only ITC. Disruption of <i>TruMDR3</i> in TIMM20092 abolished its resistance to VRC and reduced its resistance to ITC. Our study highlights TruMDR3, a newly identified transporter of the ABC family in <i>T. rubrum</i>, which can confer azole resistance if overexpressed. Finally, inhibition of TruMDR3 by milbemycin suggests that milbemycin analogs could be interesting compounds to treat dermatophyte infections in cases of azole resistance. << Less
