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.展开更多
