Grass carp which survive Dactylogyrus ctenopharyngodonid infection also gain partial immunity against Ichthyophthirius multifiliis
Bibliographic record
Abstract
Dactylogyrus ctenopharyngodonid and Ichthyophthirius multifiliis are 2 important ectoparasites of fish. Both parasites can induce an immune response in fish that leads to a decrease in parasitic infection intensity and the development of resistance against parasitic reinfection. The present study evaluated whether grass carp Ctenopharyngodon idella that survived a D. ctenopharyngodonid infection could develop immunity against infection by D. ctenopharyngodonid and I. multifiliis. The results demonstrated that when grass carp were infected with D. ctenopharyngodonid, the number of red blood cells and the percentages of thrombocytes, monocytes, and neutrophils in the white blood cells increased significantly in the early stage of infection. The percentage of lymphocytes increased over time following parasitic infection. The mean infection intensity of D. ctenopharyngodonid decreased to 0 on Day 28. The activities of serum acid phosphatase, alkaline phosphatase, lysozyme, and superoxide dismutase increased significantly after D. ctenopharyngodonid infection. In addition, the grass carp that survived a previous D. ctenopharyngodonid infection could completely resist D. ctenopharyngodonid reinfection and partially resist I. multifiliis infection.

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.
