Abstract

fetched live from OpenAlex

Significance The dissemination of antibiotic resistance in pathogenic bacteria is remarkable, and antivirulence agents with novel mechanisms of action could lead to innovative therapeutic concepts. The simultaneous suppression of multiple virulence factors or pathways using small-molecule compounds is an attractive approach to reducing the virulence of Staphylococcus aureus and may offer promising therapeutic potential in combating multidrug-resistant bacteria such as methicillin-resistant S. aureus . Here we describe a conceptual breakthrough in applying chemical genetics to probe for small-molecule compounds that will suppress the expression of multiple virulence factors in S. aureus simultaneously. Compound M21 has the ability to reverse virulent S. aureus to a nonvirulent state, as demonstrated in a mouse model of infection.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
