Prevalence and distribution of Baylisascaris procyonis in urban raccoons (Procyon lotor) in Winnipeg, Manitoba.
Bibliographic record
Abstract
The prevalence of Baylisascaris procyonis was estimated in the urban raccoon population of Winnipeg through the fecal flotation of raccoon feces collected at active latrines and through gross postmortem and fecal flotation of samples collected from nuisance raccoons. Fecal flotation of latrine-collected feces was positive in 33 of 89 samples and, of 52 latrines identified, 26 were positive on 1 or more occasions. Trapped individual raccoons subjected to postmortem examination were positive in 57 of 114 animals captured. Comparing a single fecal flotation to the gold standard of finding adult worms in the small intestine had a sensitivity of 78.9% and specificity of 92.9%. This study suggests that carriage of Baylisascaris procyonis is widespread in raccoons in the Winnipeg urban ecosystem. Raccoon latrines in Winnipeg should be treated as infectious sites and efforts should be made to limit access of pets and people at risk to those sites.

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.
