title: The postantifungal effect of 5-fluorocytosine on Candida albicans.
abstract: The in-vitro postantifungal effect (PAFE) of 5-fluorocytosine for Candida albicans for short periods of time was investigated. Yeast cells were exposed for 0.5, 1 or 2 h to a range of concentrations (0.1-3.2 mg/L) of 5-fluorocytosine. The PAFE was quantitated by determinations of the number of colony forming units at hourly intervals (0-10 h) after removal of the drug by dilution. The length of the PAFE was dependent upon the concentration of 5-fluorocytosine and the duration of exposure. An exposure time of 0.5 h resulted in PAFE's ranging from 0 to 4.2 h. Exposure times of 1 and 2 h resulted in longer PAFEs and in many instances suppression of cell growth was seen for the entire evaluation period (up to ten hours).
