Antimicrobial Resistance of <i>Campylobacter jejuni</i> subsp. <i>jejuni</i> Strains Isolated from Humans in 1998 to 2001 in Montreal, Canada
Bibliographic record
Abstract
The rates of resistance of 51 to 72 human strains of Campylobacter jejuni subsp. jejuni isolated annually from 1998 to 2001 in Montréal, Québec, Canada, varied from 1 to 12% for erythromycin, 43 to 68% for tetracycline, and 10 to 47% for ciprofloxacin. In the last years of the study, there was a significant increase in the rate of resistance to ciprofloxacin (P = 0.00003) but not in the rate of resistance to erythromycin (P = 0.056) or tetracycline (P = 0.095) compared to the rate obtained in the first years. All 51 C. jejuni strains isolated in 2001 were susceptible to gentamicin, amoxicillin-clavulanic acid, imipenem, and meropenem. From 1999 to 2001, 74 strains of C. jejuni acquired abroad were significantly more resistant to ciprofloxacin than 109 strains of C. jejuni acquired locally (66 versus 9%, P < 0.00001) but were not significantly more resistant to erythromycin (1 versus 6%, P = 0.15) or to tetracycline (55 versus 58%, P = 0.87).

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.
