Abstract

A Candida krusei strain from a patient with acute myelogenous leukemia that displayed reduced susceptibility to echinocandin drugs contained a heterozygous mutation, T2080K, in FKS1. The resulting Phe655-->Cys substitution altered the sensitivity of glucan synthase to echinocandin drugs, consistent with a common mechanism for echinocandin resistance in Candida spp.
