Аннотация:Candida albicans biofilms are generally considered to be resistant to azole antifungal agents but susceptible to echinocandins. We demonstrate that in a sequential therapy regimen, treatment with fluconazole first followed by caspofungin leads to a significant decrease of the efficacy of this echinocandin. Cellular stress responses induced by high fluconazole concentrations and mediated by Hsp90 and calcineurin play an important role in this phenomenon.
