The antimycotic activity of 5-fluorocytosine

AUTOR(ES)
RESUMO

5-Fluorocytosine (5 FC) showed marked in vitro activity against nearly all the clinical isolates of Candida and Cryptococcus examined; the required minimal inhibitory concentration was usually below 2 μg/ml and the minimal cidal concentration below 10 μg/ml. The drug had limited activity towards Aspergillus species and dermatophytes. Strains of Candida and other fungi with greatly enhanced resistance were fairly readily obtained by successive cultures on increasingly high concentrations of 5-fluorocytosine.
