Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) has been demonstrated serologically as early as 1979 in Canada, in the 1980's in other regions of North America, Europe and east Asia, in China in the mid-1990's and in Thailand in 1989 (Thanawongnuwech et al., 2004).PRRSV belongs to the family Arteriviridae, genus Arterivirus, generally divided into two major genotypes, European (EU or Type I) and North America (NA or Type II) and continues to be an economically significant swine disease particularly called porcine respiratory disease complex (PRDC) characterized by slow growth, decreased feed efficiency, anorexia, fever, cough and dyspnea in weaning to finishing pigs.Reproductive failures in sows and temporary infertility in boars are also prominent in naïve breeders.PRRSV antigenic and genetic heterogeneities as well as quasispecies evolution are documented (Goldberg et al., 2003;Schommer and Kleiboeker, 2006).In addition, co-existence of the two genotypes or more than one strains become potentially problematic since cross-protection among strains does not exist (Thanawongnuwech et al., 2004).Evidently, recombination between the Chinese modified live virus (MLV) vaccine and a local strain was demonstrated in the field when the MLV vaccine was heavily implemented during the PRRSV epidemic in China (Li et al., 2009).Additional information from the Chulalongkorn University-Veterinary Diagnostic Laboratory (CU-VDL) indicates increasing evidence of mixed infections among PRRSV strains within the same herd, causing difficulty for the control strategies either using vaccines or management strategies.

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.
