摘要
Minimal Inhibitory Concentrations to 5-fluorocytosine (FC) of 89 isolates of Candida sp and I I of Cryptococcus neoformans were determinate using the standardised microbroth method M27-A (NCCLS). Only one of 63 isolates of C albicans was resistant to FC. C krusei showed the lowest susceptibility with a geometric mean of 9.2 mug/ml (MIC50% 8 mug/ml), meanwhile the other species were full susceptible (MIC less than or equal to 0.125 mug/ml) No resistances were found in C. neoformans (MIC 50% = 4 mug/ml). Yeasts isolates from Chile and Spain where the clinical use of FC is uncommon are exceptional, except with C. krusei.
