Fungal drug resistance has become an increasingly serious problem with the wide use of antifungal drugs and the adaptive evolution of fungi. Resistance to all commonly used antifungal drugs has been reported, and the development of non-traditional antifungal drugs is urgently needed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Minimal inhibitory concentrations (MICs) of clinical pathogenic fungi were assessed by broth dilution antifungal susceptibility testing.
