Abstract
With the majority of Canadian Campylobacter jejuni infections resulting from contaminated poultry, I investigated how the strain NCTC 11168 capsular heptose modulates host macrophage activation, and bacterial clearance. Activation was assessed by ELISAs, Griess assays, qRT-PCR, and cytokine multiplex, while looking at adhesion to, uptake by, and survival within host macrophages. The heptose was immunosuppressive in chicken, but not human, macrophages and did not significantly impact clearance by tested host macrophages. It is also likely that heptose biosynthesis enzymes engage in substrate channelling, as previous data indicates that these enzymes have a means to limit degradation of unstable intermediates within the bacterial cytosol. Interactions between heptose biosynthesis enzymes were assessed by surface plasmon resonance, which indicates that enzymes in the heptose modification pathways can bind. This work determines how the capsular heptose alters the activity of host macrophages, while investigating if enzymatic interactions can be exploited to modulate heptose production.

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 it
