Abstract

fetched live from OpenAlex

Two aborted bovine fetuses were submitted (6 mo apart) with portions of their chorioallantois for postmortem examination. In both cases, microscopic examination revealed large numbers of gram-negative bacilli in the chorionic vessels and, to a lesser extent, in capillaries and venules of fetal organs of one fetus; the bacteria were not associated with noticeable inflammation or necrosis. Salmonella enterica subsp. enterica serovar Kingston was isolated from the placenta, abomasal contents, lung, and liver in case 1; Salmonella serovar Kedougou was isolated from the abomasal contents, lung, and liver in case 2. Both are rare serovars that have been isolated from various species but are not known to cause clinical disease in cattle, and, to our knowledge, have not been reported as the cause of abortion in dairy cattle.

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.

Not 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.
