Pathological Findings of Pigs Infected with Porcine Circovirus Type 2
Bibliographic record
Abstract
In 1998, histopathological examinations of 6 weaned, stunted pigs on 2 farms in Mie Prefecture revealed depletion of lymphocytes in the lymphoid follicles and grape-shaped basophilic intracytoplasmic inclusion bodies in the mononuclear cells of the lymphoid organs. Electron microscopy revealed a large number of virus particles (about 17.5nm in diameter) arranged in rope-like structures in the intracytoplasmic inclusion bodies. Immunohistochemical staining with a convalescent serum of pigs recovered from post-weaning multisystemic wasting syndrome (PMWS) and in situ hybridization with a DNA probe based on the nucleotide sequence of porcine circovirus type 2 (PCV-2) showed the virus to be PCV-2. Characteristic PCV-2 DNA was detecteed by PCR. Clinical and pathological findings of pigs in this study were similar to those obtained from cases of PMWS in Canada, the United States, and Europe, although, in this instance, pathogenic organisms other than PCV-2 also were detected.

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.
