Abstract
Ostriches were inoculated with a laboratory-derived highly pathogenic avian influenza (HPAI) virus of emu origin, A/emu/TX/39924/93 (H5N2) clone c1B. The aim of this study was to evaluate the pathogenicity of this isolate for ostriches and assess the ability of routine virological and serological tests to detect infection. Avian influenza virus (AIV) was isolated from cloacal and tracheal swabs from 2 to 12 days post-infection. AIV was also isolated from brain, thymus, eyelid, spleen, ovary/testis, liver, air sac, proventriculum, duodenum, caecal tonsil, heart, pancreas, kidney, nasal gland and lung. Virus isolation was also possible from swabs of the luminal surfaces of the cloaca, jejunum, lower ileum, bursa of Fabricius, trachea and bone marrow. Birds seroconverted as early as 7 days post-infection. This study suggests that HPAI virus of emu origin replicates extensively in infected ostriches without causing significant clinical disease or mortality.

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 it
