Histopathology of <i>Aeromonas caviae</i> Infection in Challenged Nile Tilapia <i>Oreochromis niloticus</i> (Linnaeus, 1758)
Bibliographic record
Abstract
Aeromonas caviae is one of the predominant motile aeromonads in Nile tilapia, Oreochromis niloticus . In this study, the histopathological alterations in the kidney, liver and pancreas of O. niloticus juveniles experimentally challenged with α-haemolytic A. caviae is described. The Nile tilapia experienced 60% mortalities at a challenge dose of 6×10 8 cells/fish. Post-challenge, well-defined histopathological changes were observed with nephritis and the loss of structural integrity of the kidney tissues. The liver was dispersed, necrotized and had fatty changes in the hepatic parenchyma. Inflammation of the pancreas, as well as pancreatic acinar cells and disintegration of intrahepatic exocrine pancreatic tissues, were also noted. The results, thus, demonstrated that A. caviae can cause severe damages in the kidney, liver and pancreas of O. niloticus , similar to those of other known fish bacterial pathogens.

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.
