Phylogenetic analysis and pathological characterization of fowl adenovirus isolated during inclusion body hepatitis outbreak in Tubas, Palestine.
Bibliographic record
Abstract
Fowl adenoviruses (FAdVs) associated with inclusion body hepatitis (IBH) was identified in commercial broiler chickens in Palestine. Investigated birds showed primary clinical signs and lesions of IBH including growth retardation, congested and enlarged liver with necrosis, petechial hemorrhage and basophilic intra-nuclear inclusion bodies. The mortality rate was from 15.00%. The FAdV was detected and sequenced in the liver samples of infected chicken by polymerase chain reaction using hexon gene-specific primers. Phylogenetic analysis revealed that FAdVs belong to FAdV-D serotype 10, clustered within the European highly pathogenic isolates. The highest nucleotide sequence similarity was 99.48% with highly pathogenic FAdV-D serotype 10 detected from infected chicken in Poland (GenBank: LN907532.1) and FAdV-D from infected chicken in Sweden (GenBank: HE961828.1). The lowest similarity was 93.46% with Canadian FAdV-D (GenBank: EF685576.1). In conclusion, this is the first report describing the presence of IBH revealing that the causative virus is closely similar to the highly pathogenic FAdV-D serotype 10 of IBH in broiler chickens in Palestine.

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.
