Low Sensitivity of Antemortem Gill Biopsies For the Detection of Subclinical<i>Pseudodactylogyrus bini</i>Infestations in American Eels (<i>Anguilla rostrata</i>)
Bibliographic record
Abstract
The objectives of this study were twofold: to determine the sensitivity of gill biopsies used for the screening of Pseudodactylogyrus bini in subclinically infested American eels (Anguilla rostrata) and to evaluate the effect of bath anesthesia on the proportion of infested eels. Fifty-four eels were euthanized following either intracoelomic injection of T61 or deep anesthesia with tricaine methanesulfonate. Proportions of eels infested by P. bini diagnosed by gill biopsies taken through the gill slit and by microscopic examination of the entire gill arches were compared. The euthanasia protocol had no significant effect on parasite abundance. The prevalence of monogeneans detected by examination of nonterminal antemortem gill biopsies and by complete gill examinations was 20% and 70%, respectively. The sensitivity of gill biopsies (29%) to detect P. bini in subclinically infested eels is therefore low, and should be used for group screening rather than individual screening.

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.
