Acquisition of Host Plasmin Activity by the Swine Pathogen<i>Streptococcus suis</i>Serotype 2
Bibliographic record
Abstract
In this study, the plasminogen-binding activity of Streptococcus suis serotype 2 was investigated. Bound human plasminogen was activated by purified streptokinase, urokinase, or Streptococcus dysgalactiae subsp. equisimilis culture supernatant. Both human and porcine plasminogen were bound by S. suis. Binding was inhibited by epsilon-aminocaproic acid, and the plasminogen receptor was heat and sodium dodecyl sulfate resistant. One of the receptors was identified as glyceraldehyde-3-phosphate dehydrogenase. S. suis-associated plasmin activity was capable of activating free plasminogen, which in turn could contribute to degradation of fibronectin. This is the first report on the plasminogen-binding activity of S. suis. Further studies may reveal a contribution of this activity to the virulence of S. suis.

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.
