ABSTRACT: Background: Azole-resistance is increasingly reported in Aspergillus fumigatus infections. It remains challenging to rapidly assess antifungal susceptibility to initiate the appropriate therapy. The aim of this study was to map the proteomic differences of azole-susceptible and -resistant strains. Methods: Proteomic studies were performed with ultra-performance liquid chromatography tandem mass-spectrometry (UPLC-MS/MS). Results: UPLC-MS/MS detected 7899 peptides, of which 1792 peptides had a significantly different abundance (p A. fumigatus resistance. Conclusions: UPLC-MS/MS provided proof-of-concept that the proteome of azole-resistant A. fumigatus is diverse enough to serve as a diagnostic tool.
