title: Antifungal susceptibility testing of Candida albicans by flow cytometry.
abstract: Antifungal susceptibilities of 28 Candida albicans isolates and two quality control strains to amphotericin B and fluconazole were determined by flow cytometry and microdilution method. Minimum inhibitory concentrations (MICs) obtained by flow cytometry were compared with the results obtained by The National Committee for Clinical Laboratory Standards Subcommittee (NCCLS) broth microdilution method. The agreement of results (within two dilution) obtained was found as 96 and 93% for amphotericin B and fluconazole, respectively. At least 24 h incubation was required for reading the microdilution assays. Four hours of incubation was required for fluconazole, whereas 2-h incubation was sufficient for amphotericin B to provide MIC by flow cytometry. Results of this study show that flow cytometry provides a rapid and sensitive in vitro method for antifungal susceptibility testing of Candida albicans isolates.
