Abstract

Candida auris is a newly emerged pathogenic microbe, having been identified as a medically relevant fungus as recently as 2009. It is one of the most drug-resistant yeast species known to date and its emergence and population structure are unusual. Because of its recent emergence, we are largely ignorant about fundamental aspects of its general biology, life cycle, and population dynamics. Here, we report the karyotype variability of 26 C. auris strains representing the four main clades. We demonstrate that all strains are haploid and have a highly plastic karyotype containing five to seven chromosomes, which can undergo marked alterations within a short time frame when the fungus is put under genotoxic, heat, or osmotic stress. No simple correlation was found between karyotype pattern, drug resistance, and clade affiliation indicating that karyotype heterogeneity is rapidly evolving. As with other Candida species, these marked karyotype differences between isolates are likely to have an important impact on pathogenic traits of C. auris.

  • The karyotypic plasticity displayed by C. auris in response to stressors may contribute to this organism's ability to adapt and persist in the skin niche.

    “In addition, the karyotypic plasticity displayed by C. auris in response to stressors may contribute to this organism’s ability to adapt and persist in the skin niche (23).”

    From Candida auris Forms High-Burden Biofilms in Skin Niche Conditions and on Porcine Skin (2020) · cites this paper as [23]

    The Results section (‘C. auris undergoes karyotype rearrangements in stress conditions’; page unavailable) documents stress-induced karyotype changes, and the Discussion suggests such changes might aid fitness adaptation. The Introduction describes C. auris as a skin colonizer, but the paper does not link karyotypic plasticity to adaptation or persistence in the skin niche. (LLM, conf=0.88)

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.
