Analysis of human and swine hepatitis E virus (HEV) isolates of genotype 3 in Japan that are only 81–83 % similar to reported HEV isolates of the same genotype over the entire genome
Bibliographic record
Abstract
Full-length sequences were determined for a human hepatitis E virus (HEV) isolate (HE-JA04-1911) and two swine HEV isolates (swJ8-5 and swJ12-4) that belong to one of three clusters within genotype 3 in Japan and are close to Spanish isolates according to their partial sequences. The three HEV isolates were 89.7-92.9 % identical to each other, but only 80.7-83.0 % similar to 21 HEV strains of the same genotype isolated in Canada, Kyrgyzstan, the USA and Japan over their entire genome. On comparison with HEV isolates whose partial sequence is known, the HE-JA04-1911, swJ8-5 and swJ12-4 isolates segregated into a phylogenetic cluster consisting of human and swine HEV isolates in Japan and the UK, with identities of 89.8-100 % and 87.9-92.4 %, respectively. Genotype 3 HEV isolates were found to be markedly heterogeneous. The UK-isolate-like HEV strains in Japan may have originated from the UK via the importation of pigs since 1900.

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.
