Abstract

Candida infections frequently involve drug-resistant biofilm growth on device surfaces. Glucan synthase gene FKS1 has been linked to triazole resistance in Candida biofilms. We tested the impact of FKS1 modulation on susceptibility to additional antifungal classes. Reduction of FKS1 expression rendered biofilms more susceptible to amphotericin B, anidulafungin, and flucytosine. Increased resistance to anidulafungin and amphotericin B was observed for biofilms overexpressing FKS1 . These findings suggest that Candida biofilm glucan sequestration is a multidrug resistance mechanism.

  • Genes involved in production and delivery of β-1,3-glucans include the synthase-encoding gene FKS1 and the genes BGL2, XOG1, and PHR1.

    “Genes involved in production and delivery of β-1,3-glucans include the synthase-encoding gene FKS1 and the genes BGL2, XOG1, and PHR1, which encode proteins involved in the modification and transport of β-glucans (132, 189).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
