Abstract

Antifungal susceptibility testing of Candida spp has been standardized and refined and now may play an important role in managing Candida infections. Important new developments include standardizing methods for testing echinocandins, fluconazole, and voriconazole and establishing interpretive breakpoints for these agents. Refinements in broth microdilution technology include the ability to read results after 24-hour incubation for several agents, addition of new azoles and echinocandins to commercially available microdilution trays, and automation of the entire testing process. Cross-resistance studies have identified important relationships among the triazole antifungals, and international collaboration offers the promise of harmonization and the development of an international standard for the testing of yeasts.
