Differential viral haemorrhagic septicaemia virus genotype <scp>IV</scp>b infection in fin fibroblast and epithelial cell lines from walleye, <i><scp>S</scp>ander vitreus</i> (<scp>M</scp>itchill), at cold temperatures
Bibliographic record
Abstract
A cell line, WE-cfin11e, with an epithelial-like morphology was developed from a caudal fin of walleye, Sander vitreus (Mitchill), characterized as distinct from the established walleye caudal fin fibroblast-like cell line, WE-cfin11f, and compared with WE-cfin11f for susceptibility to VHSV IVb. Immunocytochemistry and confocal microscopy were used to localize the intermediate filament protein, vimentin, the tight junction protein, zonula occludens-1 (ZO-1), the extracellular matrix protein, collagen I, and the viral protein, G. Although both cell lines contained vimentin, only WE-cfin11e stained for ZO-1 and only WE-cfin11f stained for collagen I. Ascorbic acid increased the accumulation of collagen I and caused the appearance of collagen fibres only in WE-cfin11f cultures. At 14 °C, both cell lines produced VHSV IVb, but the infection developed more rapidly in WE-cfin11f. At 4 °C, both cell lines became infected with VHSV IVb as judged by the expression of viral proteins, N and G, but only WE-cfin11f produced virus. The results suggest that cold temperatures can modulate viral tropism.

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.
