  1. MIC minimal inhibitory concentration
  2. aResistance rate was based on the intrinsic resistance of C. krusei and did not follow the actual MICs
  3. bThe breakpoints of Candida spp. according to the manufacturer’s instructions of ATB FUNGUS 3 system
  4. cThe difference of resistance rate between children and adults was analyzed by chi square test
  5. eC. parapsilosis and others isolates (C. guilliermondii (3), C. haemulonii (1) and C. inconspicua (1)) were susceptible to five antifungal agents (100%), so the results were not listed
