Synergistic Activities of Fluconazole and Voriconazole with Terbinafine against Four Candida Species Determined by Checkerboard, Time-Kill, and Etest Methods

ABSTRACT The in vitro activities of fluconazole or voriconazole plus terbinafine were evaluated against 20 Candida isolates by the checkerboard, time-kill, and Etest methods. Synergism (C. albicans, C. glabrata, and C. tropicalis) and indifference (C. krusei) were observed. Correlation among methods was good. The Etest is a suitable method to determine drug interactions.
