Trichophyton rubrum Azole Resistance Mediated by a New ABC Transporter, TruMDR3.

ABSTRACT: The mechanisms of terbinafine resistance in a set of clinical isolates of Trichophyton rubrum 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 T. rubrum to develop resistance through multidrug efflux transporters. The introduction of a T. rubrum cDNA library into Saccharomyces cerevisiae 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 T. rubrum genome, we performed a BLASTp analysis of Aspergillus fumigatus, Candi
