Abstract

Candida auris , a new multidrug-resistant Candida spp. which is associated with invasive infection and high rates of mortality, has recently emerged. Here, we determined the virulence factors (germination, adherence, biofilm formation, phospholipase and proteinase production) of 16 C. auris isolates and their susceptibilities to 11 drugs belonging to different antifungal classes, including a novel orally bioavailable 1,3-β- d -glucan synthesis inhibitor (SCY-078). We also examined the effect of SCY-078 on the growth, ultrastructure, and biofilm-forming abilities of C. auris . Our data showed that while the tested strains did not germinate, they did produce phospholipase and proteinase in a strain-dependent manner and had a significantly reduced ability to adhere and form biofilms compared to that of Candida albicans ( P = 0.01). C. auris isolates demonstrated reduced susceptibility to fluconazole and amphotericin B, while, in general, they were susceptible to the remaining drugs tested. SCY-078 had an MIC 90 of 1 mg/liter against C. auris and caused complete inhibition of the growth of C. auris and C. albicans . Scanning electron microscopy analysis showed that SCY-078 interrupted C. auris cell division, with the organism forming abnormal fused fungal cells. Additionally, SCY-078 possessed potent antibiofilm activity, wherein treated biofilms demonstrated significantly reduced metabolic activity and a significantly reduced thickness compared to the untreated control ( P < 0.05 for both comparisons). Our study shows that C. auris expresses several virulence determinants (albeit to a lesser extent than C. albicans ) and is resistant to fluconazole and amphotericin B. SCY-078, the new orally bioavailable antifungal, had potent antifungal/antibiofilm activity against C. auris , indicating that further evaluation of this antifungal is warranted.

  • Ibrexafungerp displays activity against biofilms formed by different Candida species, including C. albicans, C. parapsilosis, C. tropicalis, C. glabrata, and C. auris.

    “Regarding its anti-biofilm activity, somewhat unsurprisingly since it shares the same target with echinocandins, ibrexafungerp has been shown to display activity against biofilms formed by different Candida species, including C. albicans, C. parapsilosis, C. tropicalis, C. glabrata [44], and most recently C. auris [45].”
  • SCY-078 appears to be active against echinocandin-resistant and azole-resistant Candida strains, including C. auris.

    “Importantly, SCY-078 appears to be active against echinocandin-resistant and azole-resistant Candida strains, including C. auris [111,112,113].”

    From Treatment of Invasive Candidiasis: A Narrative Review (2018) · cites this paper as [112]

  • Exposure to various cues that induce C. albicans filamentation does not induce morphogenesis in C. auris, suggesting divergence in the circuitry governing the yeast-to-filament transition between the two Candida species.

    “However, exposure to various cues that induce C. albicans filamentation does not induce morphogenesis in C. auris, suggesting divergence in the circuitry governing the yeast-to-filament transition between the two Candida species (23).”

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.
