An Atypical Presentation of Streptococcus equi subsp. equi in a Quarter Horse Gelding
Bibliographic record
Abstract
A Quarter Horse gelding presented to Cornell University's Equine and Nemo Fann Animal Hospital Emergency Service for a I week history of cranial nerve VII paralysis, intermittent fever, and discharge from the right ear. Otitis media was presumptively diagnosed by the referring veterinarian. Culture of the aural discharge resulted in mixed bacterial growth, primarily Escherichia coli. He was treated with flunixin meglumine and trimethoprim sulfa without improvement. On presentation, the patient was admitted into an isolation stall and was bright, alert, and responsive. Physical examination abnormalities were: right cranial nerve VII paralysis, moderate amount of discharge from the right ear that was sensitive to the touch, trace amounts of bilateral white nasal discharge, and subtle right-sided head tilt. Endoscopic evaluation revealed many abnormalities of his right guttural pouch, including a hyperemic, proximally inflamed temporohyoid bone mucosa, and a moderate amount of mucopurulent discharge. The right guttural pouch was sampled and flushed, to confirm a presumptive Streptococcus equi subsp. equi infection. The patient was started on penicillin G potassium and continued to receive flunixin meglumine, omeprazole, and lubrication for his right eye due to insufficient blink. Polymerase chain reaction (PCR) and culture of the guttural pouch debris confirmed an infection of Streptococcus equi subsp. equi. During hospitalization the guttural pouches were repeatedly flushed with saline and treated with penicillin-dihydrostreptomycin in oil. The facial nerve paralysis and otitis media resolved. The guttural pouches normalized and were PCR and culture negative for Streptococcus equi subsp. equi on day 17.

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.
