Молекулярно-генетический анализ геномов вирусов респираторно-репродуктивного синдрома свиней и цирковируса второго типа, циркулирующих на территории российской федерации
Bibliographic record
Abstract
The molecular genetic analysis of the genomes of the virus of porcine reproductive respiratory syndrome (VPRRS) and porcine circovirus type 2 (PCV-2) circulating in the area of the Russian Federation was discussed. The results of this work showed the circulation of the strains of the European genotype VPRRS similar to those found in France and Denmark from 1998 to 2001. The homology of the fragment of one of the genes between the Russian isolates and the vaccine strain Porcilis PRRS (Intervet) was found. It requires further study. The strains representing the North American genotype VPRRS 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, UK, USA, isolated during the period from 2004 to the present time. The second group consists of sequences of the viruses isolated in 2000-2012 in Canada, the U.S., China, and South Korea (genotype 2a). The third group is formed by highly pathogenic isolates in 2013 from China (highly pathogenic genotype 2c). The circulation of all three known genotypes of PCV-2: 2a, 2b, and 2c in Russian Federation was demonstrated.

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.
