Effect of fox, pig, sheep, and poultry bile on the establishment of domestic and sylvatic species of <i>Trichinella</i> in rats
Bibliographic record
Abstract
Most sylvatic species of Trichinella are known to have poor infectivity to rats, but in the present study oral administration of bile from other hosts appeared to modify this infectivity. A total of 75 rats were inoculated in groups of 25 with 3 species of Trichinella (T. spiralis, T. nativa, and T. nelsoni) and each group of rats was given per os daily doses of bile from pig, sheep, chicken and fox respectively (4 x 5 rats). As a control 1 group of 5 rats was given daily doses of water. Whereas, the addition of bile did not increase the establishment of T. spiralis, fox bile had a significant positive effect on the establishment of muscle larvae of T. nativa and T. nelsoni. Addition of bile to cultures of the same Trichinella species had an overall negative effect on the in vitro survival of larvae. The present observation that carnivore bile favours the establishment of sylvatic Trichinella may explain why carnivores are equally receptive to all Trichinella species.

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.
