Molecular genetic analysis of genomes of porcine respiratory and reproductive syndrome viruses and porcine circovirus type 2 circulating on the territory of the Russian federation
Bibliographic record
Abstract
A molecular genetic analysis of genomes of porcine reproductive respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV-2) circulating in the territory of the Russian Federation is given. The results of the study showed the presence of circulation of European genotypes of PRRSV strains that are similar to isolates found in France and Denmark from 1998 to 2001. We explained the homology of a fragment of one of the genes between the Russian isolates and the vaccine strain used in Porcilis PRRS (Intervet) vaccine, but this requires further study. Strains of the North American genotype of PRRS were not found. The PCV-2 genomes fall into three separate groups. One (genotype 2b) is formed by isolates in Malaysia, Brazil, Switzerland, China, Slovakia, the United Kingdom, and the United States, which were isolated during the period from 2004 to the present time. The second group consists of the field sequences of viruses isolated in 2000–2012 in Canada, the United States, China, and South Korea (genotype 2a). The third group is formed by highly pathogenic isolates evolved in 2013 in China (genotype 2c). The circulation of all three known genotypes of PCV-2-2a, 2b, and 2c-in the Russian Federation was shown.

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.
