Genetic diversity of bovine viral diarrhea virus in cattle from Mexico
Bibliographic record
Abstract
Bovine viral diarrhea virus (BVDV) infects cattle populations worldwide, causing significant economic losses though its impact on animal health. Previous studies have reported the prevalence of BVDV species and subgenotypes in cattle from the United States and Canada. We investigated the genetic diversity of BVDV strains detected in bovine serum samples from 6 different Mexican regions. Sixty-two BVDV isolates from Mexico were genetically typed based on comparison of sequences from the 5' untranslated region (5'-UTR) of the viral genome. Phylogenetic reconstruction indicated that 60 of the samples belonged to the BVDV-1 genotype and 2 to the BVDV-2 genotype. Comparison of partial 5'-UTR sequences clustered 49 samples within BVDV-1c, 8 samples within BVDV-1a, 3 samples within BVDV-1b, and 2 samples clustered with the BVDV-2a subgenotypes. Our study, combined with information previously published on BVDV field strain diversity in the United States and Canada, benefits the development of effective detection assays, vaccines, and control programs for North America.

How this classification was reachedexpand
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.
