  • a MIC50, MIC at which 50% of the isolates were inhibited.

  • b FICs were based on the MIC80s for all isolates except those of C. albicans, C. parapsilosis, and Cryptococcus neoformans, for which MIC100s were used (Table 2).

  • c NA, not applicable. Itraconazole MICs for these organisms were at the lowest concentration tested; therefore, the drug interaction could not be determined.
