Inhibition of germfree extracts derived from fermented milk on flaA σ~(28) promoter in Campylobacter jejuni
Bibliographic record
Abstract
To study the inhibition of germfree extracts derived from milk fermented by lactic acid bacteria(LAB) on virulence gene flaA expression of foodborne pathogen bacteria Campylobacter jejuni,a luminescent phenotype fusion between the flaA σ28 promoter and a promoterless luxCDABE cassette carried on the plasmid pRYluxCDABE in Campylobacter jejuni was used.Through evaluation of the bioluminescence,the effect of germfree extracts derived from milk fermented by lactic acid bacteria (LAB)(5 Bifidobacterium strains and 6 Lactobacillus strains) was assessed on flaA σ28 promoter activity.The results showed that gremfree extracts of milk fermented by LAB were found to have a significant(P0.05) inhibitive effect on the expression of flaA σ28 promoter,and down-regulate virulence gene flaA expression.

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.
