Isolation of Methicillin-Resistant Staphylococcus aureus from the Environment in a Veterinary Teaching Hospital
Bibliographic record
Abstract
After recognition of a cluster of methicillin-resistant Staphylococcus aureus (MRSA) infection in horses and humans at the Ontario Veterinary College Veterinary Teaching Hospital, environmental contamination with MRSA was evaluated. A total of 260 environmental surfaces were sampled during periods when MRSA-infected horses were hospitalized, and MRSA was isolated from 25/260 sites (9.6%). The most commonly contaminated sites were stalls housing MRSA-positive horses, but other stalls, medical equipment, personal items, and equine restraint devices also were contaminated. The role of the environment in the transmission of MRSA infection to horses or humans is unclear. However, relatively widespread contamination of the hospital environment, as apparently occurs when infected horses are hospitalized, suggests that the environment may be an important source of MRSA infection. This possibility must be taken into consideration when designing infection control and disinfection protocols.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
