Molecular analysis of the S glycoprotein gene of bovine coronaviruses isolated in Japan from 1999 to 2006
Bibliographic record
Abstract
In total, 55 isolates of Bovine coronavirus (BCoV) were collected from cases of enteric and respiratory disease occurring between 1999 and 2006 in Japan. Phylogenetic analysis of the polymorphic region of the S glycoprotein gene of these isolates, together with those of other known strains, classified the BCoV strains and isolates into four clusters. Recent field isolates display distinctive genetic divergence from the prototype enteric BCoV strains--Mebus, Quebec, Kakegawa, F15 and LY138--and have diverged in three different aspects over 8 years. These data suggested that the genetic divergence in the polymorphic region of the S glycoprotein has progressed considerably; thus, molecular analysis of this region should be useful in investigating the molecular epidemiology of BCoV. In addition, based on the differences in amino acids among the isolates, our study did not reveal the presence of certain genetic markers of pathogenicity and clinical symptoms in this polymorphic region.

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.
