Abstract
Summary Infection with cytomegaloviruses is a common occurrence in a variety of animal species, yet there are no reports of their occurrence in the bovine species. For the first time, cytomegalic inclusion bodies were detected in lungs, kidney, liver, myocardium and spleen of a bovine fetus, aborted at approximately 6 1/2 months gestation. Electronmicroscopic studies revealed the presence of viral particles in nuclei and cytoplasm of affected cells. No apparent clinical disease was observed in the dam or other cows of the herd, nor did any further losses occur. Zusammenfassung Cytomegalovirusinfektion als Verwerfensursache beim Rind Cytomegalovirusinfektionen sind bei fast allen Tierarten und beim Menschen beschrieben worden, jedoch fehlen Berichte über solche Infektionen bei Rindern. Erstmals wird über cytomegale Einschlüsse in Lunge, Niere, Leber, Herz und Milz eines 6 bis 7 Monate alten abortierten Rinderfetus berichtet. Mit Hilfe des Elektronenmikroskopes konnte die Anwesenheit von Viruspartikeln im Nukleus und im Zytoplasma veränderter Zellen nachgewiesen werden. Klinische Zeichen einer Erkrankung traten weder bei der Kuh, die abortierte, noch bei anderen Kühen in der Herde auf. Weitere Aborte wurden nicht beobachtet. Résumé Infection à Cytomegalovirus à l'origine d'avortement chez le bovin Les infections à Cytomegalovirus ont été décrites chez presque toutes les espèces animales et chez l'homme; des données de telles infections font toutefois défaut chez le bovin. On décrit pour la première fois des inclusions cytomegales dans les poumons, les reins, le foie, le coeur et la rate chez un foetus de bovin avorté à 6–7 mois. On a pu démontrer la présence de particules virales dans le nucleus et le cytoplasme des cellules atteintes au moyen du microscope électronique. Aucun signe clinique ne se manifesta aussi bien chez l'animal avorté que dans le reste du troupeau. On n'a pas observé d'autres avortements. Resumen Infecciones a virus cytomegálico se han descrito en casi todas las especies animales y en el hombre, pero faltaban hasta la fecha los informes sobre tales infecciones en vacas. Por vez primera se informa sobre inclusiones cytomegálicas en pulmón, riñón, hígado, corazón y bazo de un feto abortado de vaca de unos 6 o 7 meses de edad. Con ayuda del microscopio electrónico se pudo probar la presencia de partículas virales en el núcleo y en el citoplasma de las células alteradas. Signos clínicos de una enfermedad no se registraron ni en la vaca que abortó ni en otras vacas de la manada. No se observaron más casos de aborto.

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.
