Abstract

CLSI M27M44S—Performance Standards for Antifungal Susceptibility Testing of Yeasts includes minimal inhibitory concentration, zone diameter, and quality control tables developed following the guidance in CLSI M27 and CLSI M44. The data in the tables are valid only when the methodologies in CLSI M27 and CLSI M44 are followed. Users should replace previously published tables with these new tables. Changes in the tables since the previous edition was published appear in boldface type.
