Quantitative microculture system with standardized inocula for strain typing, susceptibility testing, and other...

A method for physiologic testing of Candida albicans and other yeasts is described in which inocula with reproducible cell concentrations are prepared from cultures in a glucose-limited medium and growth turbidities of test cultures in microplates are expressed quantitatively as a percentage of control growth. The method gave good within-plate and run-to-run reproducibilities and was applicable both to strain phenotype discrimination in C. albicans and to susceptibility tests of yeasts with azole antifungal agents.
