No Evidence for Resistance to Fenbendazole in <i>Trichostrongylus tenuis</i> , a Nematode Parasite of the Red Grouse
Bibliographic record
Abstract
ABSTRACT The parasitic nematode Trichostrongylus tenuis has a detrimental effect on red grouse ( Lagopus lagopus scoticus ) at the individual and population levels. Treatment using grit coated with the anthelmintic fenbendazole hydrochloride reduces parasite infection and increases grouse density. However, a frequent and low dose of anthelmintic increases selection pressure for parasite resistance, a serious practical and economic problem. We used an egg hatch assay to test resistance of T. tenuis from 12 moors in northern England, which differed in grit treatment intensity. The anthelmintic concentration that prevented 50% and 95% of T. tenuis eggs from hatching (ED 50 and ED 95 , respectively) did not differ among moors and were not related to treatment. We suggest annual monitoring and responsible anthelmintic use to prevent resistance so that medicated grit continues to enhance red grouse management.

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.
