Investigating the vector competence of the house fly (Musca domestica) for Campylobacter jejuni
Bibliographic record
Abstract
Campylobacteriosis is a severe gastroenteric disease in humans caused by the bacterium, Campylobacter jejuni, typically obtained through the ingestion of contaminated poultry products. Poultry facilities become contaminated through the introduction of pathogens, including C. jejuni, by the house fly, Musca domestica. This thesis investigates the vector competence of M. domestica for C. jejuni to determine if the bacteria survive house fly metamorphosis from larva to adult, and can multiply within adult flies to enhance transmission, and whether innate immune factors of the house fly can clear C. jejuni infections. We demonstrate that M. domestica mounts an effective innate immune response that prevents transmission of C. jejuni from larva to adult, and eliminates C. jejuni from adult house fly gastrointestinal tracts within hours. We propose that M. domestica serves as a mechanical vector, rather than as a true, amplifying, biological vector. These findings will help elucidate the elusive epidemiology of campylobacteriosis.

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.
