Abstract

Antimicrobial resistance is a public health threat associated with increased morbidity, mortality and financial burden in nursing homes and other healthcare settings 1. Residents of nursing homes are at increased risk of pathogen colonization and infection owing to antimicrobial-resistant bacteria and fungi. Nursing homes act as reservoirs, amplifiers and disseminators of antimicrobial resistance in healthcare networks and across geographical regions 2. Here we investigate the genomic epidemiology of the emerging, multidrug-resistant human fungal pathogen Candida auris in a ventilator-capable nursing home. Coupling strain-resolved metagenomics with isolate sequencing, we report skin colonization and clonal spread of C. auris on the skin of nursing home residents and throughout a metropolitan region. We also report that most Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Entobacter species (ESKAPE) pathogens and other high-priority pathogens (including Escherichia coli, Providencia stuartii, Proteus mirabilis and Morganella morganii) are shared in a nursing home. Integrating microbiome and clinical microbiology data, we detect carbapenemase genes at multiple skin sites on residents identified as carriers of these genes. We analyse publicly available shotgun metagenomic samples (stool and skin) collected from residents with varying medical conditions living in seven other nursing homes and provide additional evidence of previously unappreciated bacterial strain sharing. Taken together, our data suggest that skin is a reservoir for colonization by C. auris and ESKAPE pathogens and their associated antimicrobial-resistance genes.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • C. auris has an enhanced ability to colonize high-sweat body sites such as the axillae or inguinal crease.

    “This suggests an enhanced ability of C. auris to colonize high-sweat body sites, such as the axillae or inguinal crease, which is corroborated by clinical sampling10,19.”
  • C. auris can persist in skin tissues for months, often evading detection during routine clinical surveillance.

    “suggesting that C. auris can persist in skin tissues for months, often evading detection during routine clinical surveillance [3,12,13].”

    From Host–Candida auris interactions in the skin (2026) · cites this paper as [13]

  • In murine skin, surface colonization turned negative after 2 months, but live C. auris was recovered from deep skin tissue up to 4 months after initial colonization.

    “skin surface colonization of the murine skin was shown to turn negative after 2 months, but live C. auris was recovered from deep skin tissue up to 4 months after initial colonization”

    From Host–Candida auris interactions in the skin (2026) · cites this paper as [13]

  • Patients with C. auris skin colonization were frequently co-colonized with multidrug-resistant gram-negative bacteria, including Proteus mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Providencia stuartii, and Morganella morganii.

    “Patients with C. auris skin colonization were frequently co-colonized with multidrug-resistant gram-negative bacteria, including Proteus mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Providencia stuartii, and Morganella morganii (Fig 2) [12,13].”

    From Host–Candida auris interactions in the skin (2026) · cites this paper as [13]

  • Candida auris can persistently colonize human skin.

    “C. auris exhibits a particular tropism for the skin6–8. It is capable of persistent colonization in niches such as the axillae and groin”

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.
