Novel FKS mutations associated with echinocandin resistance in Candida species.
We studied three clinical isolates of Candida spp. (one C. tropicalis isolate and two C. glabrata isolates) from patients with invasive candidiasis. The first isolate emerged during echinocandin treatment, while the others emerged after the same treatment. These strains harbored an amino acid substitution in Fksp never linked before with reduced echinocandin susceptibility in C. tropicalis or i...
متن کاملRole of FKS Mutations in Candida glabrata: MIC values, echinocandin resistance, and multidrug resistance.
Candida glabrata is the second leading cause of candidemia in U.S. hospitals. Current guidelines suggest that an echinocandin be used as the primary therapy for the treatment of C. glabrata disease due to the high rate of resistance to fluconazole. Recent case reports indicate that C. glabrata resistance to echinocandins may be increasing. We performed susceptibility testing on 1,380 isolates o...
متن کاملEchinocandin Resistance in Candida.
Invasive fungal infections are an important infection concern for patients with underlying immunosuppression. Antifungal therapy is a critical component of patient care, but therapeutic choices are limited due to few drug classes. Antifungal resistance, especially among Candida species, aggravates the problem. The echinocandin drugs (micafungin, anidulafungin, and caspofungin) are the preferred...
متن کاملDiscontinuation of echinocandin and azole treatments led to the disappearance of an FKS alteration but not azole resistance during clonal Candida glabrata persistent candidaemia.
To give an indication of a fitness cost conferred by FKS mutation-associated echinocandin resistance in Candida glabrata during human infection. Six C. glabrata clinical strains sequentially isolated from blood and a hepatic abscess in a solid organ transplant recipient were analysed. The patient had received long-term azole and echinocandin therapy for invasive aspergillosis and persistent can...
متن کاملAzole Resistance and ERG11 464 Polymorphism in Oral Candida albicans Clinical Strains Isolated in Sardinia
The in vitro activity of three different azoles (fluconazole, FLC, voriconazole, VRC and ketoconazole, KTC) was determined and correlated with the single nucleotide polymorphisms (SNPs) in a “hot spot” region of the ERG11 gene in a collection of 52 arbitrarily selected C. albicans strains isolated from Sardinian subjects with oropharyngeal candidiasis. Among the strains evaluated, 23.1% were re...
