Fowl Typhoid and Pullorum Disease
Bibliographic record
Abstract
Fowl typhoid and pullorum disease are among the most important diseases of poultry. These conditions are caused by two very closely related organisms, which were once thought to be different species but have recently been classified as biovars of Salmonella enterica subsp. enterica. Pullorum disease is usually symptomatic only in young birds. The mortality rate varies, but it can be as high as 100%. Fowl typhoid resembles pullorum disease in young birds, but it is also a serious concern in growing and adult poultry. The control of these diseases is complicated by vertical transmission: hens can become subclinically infected carriers, and pass the infections to their embryos in the egg. Fowl typhoid and pullorum disease have been eradicated from commercial poultry in many developed countries including the United States and Canada, but they may persist in backyard poultry flocks and game birds. Pullorum disease is an increasing concern in pheasant chicks. On rare occasions, these diseases have been reintroduced to commercial chicken or turkey farms.

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.
