Lymphoma in 2 black vultures
Bibliographic record
Abstract
Vultures have suffered a drastic population decline mainly due to poisoning and traumatic lesions; neoplastic diseases in these birds are rarely documented. Here we describe the clinical and pathologic findings of lymphoma in 2 free-ranging black vultures ( Coragyps atratus ). Upon initial evaluation, both birds were severely emaciated; vulture 1 had proptosis of the right eye and vulture 2 swelling of the left wing. The vultures died shortly after presentation and were autopsied. In both birds, the thymus and many other organs were expanded by poorly demarcated, white, soft masses that were composed histologically of proliferating lymphocytes of monomorphic appearance. In vulture 2, thickening of the left-wing bones appeared to be caused by periosteal reaction, associated with bone invasion by the same type of lymphocytes, and granulomatous osteomyelitis. By immunohistochemistry, neoplastic cells were reactive for CD3 and negative for PAX5. The final diagnoses were multicentric T-cell lymphoma. PCR assays for Marek disease, avian leukosis, reticuloendotheliosis, and bovine leukemia viruses were negative in both cases. To our knowledge, lymphoma has not been reported previously in vultures.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
