Rainbow trout <i>Oncorhynchus mykiss</i> (Walbaum) type IV ice‐structuring protein LS‐12 in the acute‐phase response to <i>Flavobacterium psychrophilum</i> infection
Bibliographic record
Abstract
Abstract A previous proteomic study examining the plasma acute‐phase response of rainbow trout to sterile inflammation highlighted an unidentified 9.5‐kDa spot using 2D‐PAGE, which was dramatically increased. The 15 amino acid sequence obtained from this protein spot allowed rapid amplification of cDNA ends PCR to generate a 443‐bp nucleotide sequence that was 98.6% similar to type‐4 ice‐structuring protein LS‐12 from Atlantic salmon Salmo salar Linnaeus. Quantitative reverse translation PCR and an ELISA were used to measure gene expression and plasma concentrations of LS‐12 following experimental intraperitoneal injection of rainbow trout with either 10 6 or 10 8 colony‐forming units (CFU) of Flavobacterium psychrophilum . There was no significant change in the plasma concentration of LS‐12 up to 15 days post‐infection in any group. Hepatic LS‐12 gene expression was significantly reduced at 3 and 6 days ( p < 0.001) post‐infection in fish injected with 10 8 CFU of F. psychrophilum relative to control fish, while branchial or head kidney expression was unchanged. Infected fish had significantly increased hepatic gene expression of serum amyloid A, confirming an acute‐phase response. Under the conditions used, LS‐12 is not a positive acute‐phase protein in rainbow trout.

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.
