Four genomic clades of <i>Candida auris</i> identified in Canada, 2012–2019
Bibliographic record
Abstract
Candida auris is an emerging yeast that is associated with antifungal resistance and healthcare-associated outbreaks. From 2012 to 2019, there were 24 known cases of C. auris colonization or infection in Canada. Isolates were from axilla/groin (n = 6), ear (n = 5), blood (n = 4), toe (n = 2), and a variety of other sites (n = 7). Canadian isolates belonged to the four main genomic clades: Clade I (formerly called South Asian clade, n = 12), Clade II (East Asian, n = 3), Clade III (African, n = 4), and Clade IV (South American, n = 5). Isolates within each clade were clonal; however, whole genome sequencing may be helpful in identifying clusters within healthcare facilities. LAY SUMMARY: The fungal pathogen Candida auris has caused many hospital outbreaks and is often multidrug resistant. All four major strains of C. auris were identified in Canada from 2012 to 2019. Genomic epidemiology may be useful for identifying and reducing transmission of C. auris within hospitals.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
