Azole Antifungal Resistance in Candida albicans and Emerging Non-albicans Candida Species
Within the limited antifungal armamentarium, the azole antifungals are the most frequent class used to treat Candida infections. Azole antifungals such as fluconazole are often preferred treatment for many Candida infections as they are inexpensive, exhibit limited toxicity, and are available for oral administration. There is, however, extensive documentation of intrinsic and developed resistan...
متن کاملProteomic analysis of azole resistance in Candida albicans clinical isolates.
Changes in protein expression within a matched set of Candida albicans isolates representing the acquisition of azole resistance were examined by two-dimensional polyacrylamide gel electrophoresis and peptide mass fingerprinting. Proteins differentially expressed in association with azole resistance included Grp2p, Ifd1p, Ifd4p, Ifd5p, and Erg10p, a protein involved in the ergosterol biosynthes...
متن کاملMicafungin activity against Candida albicans with diverse azole resistance phenotypes.
OBJECTIVES The purpose of this study was to investigate whether mechanisms of azole resistance in Candida albicans contribute to reduced micafungin activity in vitro. METHODS MICs were determined for a collection of strains with well-characterized mechanisms of azole resistance obtained from systemic, oral and vaginal infections. This collection of strains includes those with resistance-assoc...
متن کاملConstitutive activation of the PDR16 promoter in a Candida albicans azole-resistant clinical isolate overexpressing CDR1 and CDR2.
Candida albicans azole-resistant clinical isolates overexpressing the CDR1 and CDR2 genes (multidrug transporters) also overexpress the PDR16 gene (phosphatidylinositol transfer protein). We show here that the PDR16 promoter displays higher transcriptional activity following integration in an azole-resistant isolate than in the matched azole-susceptible one. Thus, the upregulation of PDR16 in t...
متن کاملAzole susceptibility and resistance in Candida dubliniensis.
Candida dubliniensis is a recently described species of pathogenic yeast that shares many phenotypic features with Candida albicans. It is primarily associated with oral colonization and infection in HIV-infected individuals. Isolates of C. dubliniensis are generally susceptible to commonly used azole antifungal agents; however, resistance has been observed in clinical isolates and can be induc...
