Rotavirus group C infections in neonatal and grower pigs in Australia
Bibliographic record
Abstract
BACKGROUND: Rotavirus infections of neonatal and older pigs are widely reported. Analysis of rotavirus group C prevalence and diversity has not previously been reported for Australian pig farms. METHODS: Twenty-seven farms with or without diarrhoea present among neonatal or older pigs were enrolled across eastern Australia. Fresh faecal samples were analysed by ELISA for rotavirus and RNA extractions by polyacrylamide gel electrophoresis and RT-PCR for rotavirus. Rotavirus group C samples were genotyped via sequencing. RESULTS AND CONCLUSIONS: Rotavirus infection was diagnosed in pigs on 10 of 19 farms investigated for neonatal diarrhoea, four with group A and six with group C; also among post-weaned (5- to 11-week-old) diarrhoeic pigs on two farms. Neonatal rotavirus group C infections were exclusively noted in piglets less than 1-week-old, consisting of farm infections with a single VP7 genotype (G5 or G6). Infections in post-weaned pigs were associated with multiple VP7 genotypes (G1, G3). This first report of rotavirus group C infections of Australian pigs suggests they may form a limited population of VP7 genotypes.

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.
