Reduction of salmonella contamination in pork carcasses by vaccination
Bibliographic record
Abstract
Discussion: Immunization with an avirulent live S choleraesuis vaccine has demonstrated consistent clinical and bacteriologic control of S choleraesuis infections in swine.Clinical signs, including febrile response, diarrhea and mortality, along with growth rate, are significantly improved (p<0.05).Pigs from one day of age and older may be safety vaccinated intranasally, or orally, via drinking water, against disease associated with S choleraesuis, and to reduce the culture prevalence and shedding of other serovars of Salmonellae (Nolan et al., 2000).Additionally, levels of the organism are effectively reduced in vaccinated, challenged pigs.Fecal shedding of S choleraesuis is significantly lower in vaccinated challenged pigs as compared to challenged control pigs.Organ culture prevalence is likewise dramatically lowered in vaccinated pigs.Vaccination at one day of age is at least as efficacious, and may offer even greater advantage over non vaccinated controls.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
