Bibliography

ISO 16256:2012 describes a method for testing the susceptibility to antifungal agents of yeasts, including Candida spp. and Cryptococcus neoformans, that cause infections. The reference method described here has not been used in studies of the yeast forms of dimorphic fungi, such as B. dermatitidis and/or H. capsulatum variety capsulatum. ISO 16256:2012 describes the broth microdilution reference method which can be implemented by either of two pathways. One pathway involves visual determination of MICs (CLSI method); the second pathway involves spectrophotometric determination of MICs (EUCAST method).
