<i>Bifidobacterium longum</i> subsp. <i>infantis</i> YLGB‐1496—Toxicological evaluation
Bibliographic record
Abstract
Bifidobacterium infantis YLGB-1496, originally isolated from breast milk from a Taiwanese mother, is under study for use as a probiotic. As part of safety assessment, an Ames, in vivo mouse micronucleus, and in vivo mouse spermatocyte chromosome aberration assay were conducted along with a 13-week oral rat toxicity study. B. infantis YLGB-1496 had no activity in any of the genotoxicity assays. Administration of the bacteria to Sprague-Dawley rats at doses ranging from 0 to 1.5 g/kg bw/day had no treatment-related effects on any of the endpoints measured. There appear to be no concerns for translocation or pathogenicity of B. infantis YLGB-1496 based on extensive experience with the species in general. The results of the current investigations support potential use of B. infantis YLGB-1496 as a probiotic in infant formula.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
