WebApr 5, 2010 · Candida spp. strains harboring fks mutations demonstrated elevated caspofungin MIC results (1 to ≥8 μg/ml) (Table (Table2) 2) and lower anidulafungin and micafungin MIC values (by at least 2-fold) (Table (Table3). 3). Previous reports also observed that strains possessing altered FKS usually display higher caspofungin MIC … WebJun 22, 2009 · These mutations were also found to reduce the catalytic efficiency of the enzyme (Vmax) and to influence the relative expression of FKS genes. In view of the association of FKS mutations and reduced susceptibility of 1,3-β-d-glucan synthase, an evaluation of the new CLSI echinocandin susceptibility breakpoint was conducted.

WebSix of the analysed isolates had fluconazole MICs ≥ 32 µg/mL; of them, five harboured unique PDR1 mutations. Although echinocandin resistance was not detected, three isolates had mutations in HS1-Fks1 (S629T, n = 1) and HS1-Fks2 (S663P, n = 2); one of the … WebSep 15, 2014 · Conclusions: FKS mutations were identified in 18% of 72 patients with C. glabrata candidemia. Common risk factors for FKS mutant isolates included previous echinocandin exposure, which also influenced response rates. Keywords: Candida … WebJun 30, 2024 · As expected, the rebound in fungal burden was accompanied by the emergence of reduced susceptibility to caspofungin in the yeast isolated from mouse fecal pellets, and it was often (though not always) associated with fks mutations.
