<i>Porcine Teschovirus</i> Polioencephalomyelitis in Western Canada
Bibliographic record
Abstract
Beginning in 2002, a small number of pig farms in western Canada began reporting 4-7-week-old pigs with bilateral hind-end paresis or paralysis. Low numbers of pigs were affected, some died, most had to be euthanized, and those that survived had reduced weight gains and neurological deficits. Necropsies revealed no gross lesions, but microscopic lesions consisted of a nonsuppurative polioencephalomyelitis, most severe in the brain stem and spinal cord. The lesions were most consistent with a viral infection. Tests for circovirus, Porcine reproductive and respiratory syndrome virus, coronavirus, Rabies virus, and Pseudorabies virus were negative. Using immunohistochemistry, virus neutralization, fluorescent antibody test, and nested reverse transcription polymerase chain reaction, Porcine teschovirus was identified in tissues from affected individuals. To the authors' knowledge, this is the first report of teschovirus encephalitis in western Canada and the first reported case of polioencephalomyelitis in pigs in Canada, where teschovirus was confirmed as the cause.

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.
