MIC interpretations are based on recent publications and CLSI guidelines. Susceptible-Dose Dependent (S-DD): susceptibility is dependent on achieving maximum blood levels. Newer antifungal agents with MICs above the susceptible breakpoint are reported as Nonsusceptible due to minimal data on resistance. MICs only are provided for those drugs for which no guidelines have been established.
