Isolation of Newcastle Disease Virus and Salmonella typhimurium from the Brain of Double-Crested Cormorants (Phalacrocorax auritus)
Bibliographic record
Abstract
Avian paramyxovirus type 1 (Newcastle disease virus) and Salmonella typhimurium were isolated from the brain and lung tissues of double-crested cormorants (Phalacrocorax auritus) from Lac Canard, Alberta, Canada. More than 100 birds died during this outbreak in 1999. Affected birds presented signs of central nervous system disease characterized by unilateral wing and leg paralysis. Other geographic locations in the provinces of Alberta and Saskatchewan have reported cases of cormorants suffering from diseases with signs compatible with Newcastle disease. The virus isolated in the 1999 outbreak was characterized as mesogenic. These findings suggest that other pathogens, like S. typhimurium, may influence the clinical presentation of disease caused by mesogenic strains of Newcastle disease virus in cormorants.

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.
