Loop‐Mediated Isothermal Amplification Assays for Detecting <i>Yersinia pseudotuberculosis</i> in Milk Powders
Bibliographic record
Abstract
UNLABELLED: Yersinia pseudotuberculosis is a Gram-negative foodborne pathogen that causes several diseases, such as enteritis, septicemia, and reactive arthritis. Loop-mediated isothermal amplification (LAMP) assay targeting the 16S-23S rDNA internal transcribed spacer (ITS) region was developed to detect Y. pseudotuberculosis in milk powder. The DNA amplification could be completed in 1 h, and detected by produced white precipitate visible to naked eyes. The detection limit of LAMP assay was 10(0) fg/reaction for genomic DNA, and 10(0) CFU/100 g milk powder coupled with 12 h enrichment. LAMP assay is 100 times more sensitive than conventional polymerase chain reaction method for detecting Y. pseudotuberculosis, and correctly identified 18 cases of Y. pseudotuberculosis contaminations from 236 commercial milk powder products. In conclusion, the developed LAMP assay may facilitate rapid detection of Y. pseudotuberculosis contaminations in agricultural and food products. PRACTICAL APPLICATION: Rapid and accurate detection of Yersinia pseudotuberculosis in milk products.

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.
