Abstract
Abstract Streptococcus equi subsp. zooepidemicus is an opportunistic pathogen associated with disease in a range of domestic and wild animals. Despite its importance, very limited data is available on its survival and persistence on the environment. The goal of this study was to evaluate survival of S. zooepidemicus under ideal culture conditions and farm-like setting, in various surface types. Rubber, plastic, wood, and concrete samples were sterilized and inoculated with 10 9 CFU/mL of S. zooepidemicus with or without feces, and cultured under ideal conditions (37 °C, 5% CO 2 ) or farm-like settings (20 o C on air) for a maximum period of 25 days (n = 3/material/environment/feces-group/time-point). Under ideal conditions without feces, the bacterium survived for up to 17 days on plastic and rubber surfaces, 4 days on wood and less than 1 day on concrete ( P < 0.05 between materials). Samples under ideal conditions with feces and farm-like settings without feces were negative by day 1 post-inoculation, regardless of the surface material used. Wood and concrete allowed S. zooepidemicus persistence for up to 3 days under farm-like settings when feces were present. This data suggests that environmental persistence of S. zooepidemicus is affected by surface type and incubation temperature.

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
