Molecular Characteristics of Travel-Related Extended-Spectrum- -Lactamase-Producing Escherichia coli Isolates from the Calgary Health Region
Bibliographic record
Abstract
Extended-spectrum--lactamase (ESBL)-producing Escherichia coli has recently emerged as a major risk factor for community-acquired, travel-related infections in the Calgary Health Region. Molecular character-ization was done on isolates associated with infections in returning travelers using isoelectric focusing, PCR, and sequencing for blaCTX-Ms, blaTEMs, blaSHVs, blaOXAs, and plasmid-mediated quinolone resistance deter-minants. Genetic relatedness was determined with pulsed-field gel electrophoresis using XbaI and multilocus sequence typing (MLST). A total of 105 residents were identified; 6/105 (6%) presented with hospital-acquired infections, 9/105 (9%) with health care-associated community-onset infections, and 90/105 (86%) with com-munity-acquired infections. Seventy-seven of 105 (73%) of the ESBL-producing E. coli isolates were positive for

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
