Abstract

fetched live from OpenAlex

Bacteroides fragilis strains were studied to examine carbapenemase gene (cfiA) expression and insertion sequence (IS) element promoters. High-level resistance was associated with high meropenemase activity and IS elements upstream of cfiA. Sequencing revealed two element types; IS1187 and elements related to IS942 and IS1170. The latter was implicated in the conversion to carbapenem resistance in a cfiA-positive isolate during imipenem therapy. Two strains showing low-level resistance, and strains susceptible to meropenem, did not possess IS elements upstream of cfiA. The prevalence in Nottingham of clinical isolates of B. fragilis with cfiA and efficient IS element promoters was low (0.6%).

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.
