Association of <i>Stenotrophomonas maltophilia</i> in African Catfish, <i>Clarias gariepinus</i> (Burchell, 1822) Fry Mortalities with Dropsy
Bibliographic record
Abstract
This communication reports the association of S. maltophilia in the mortalities of nursery grown African catfish Clarias gariepinus (Burchell, 1822) fries with distended abdomen and its phenotypic characterization. The gross and clinical signs observed in diseased fries were lethargy, body discolouration, mild fin/tail rot, distended abdomen, swelled intestine and other internal organs, and visceral haemorrhages. The abdominal cavity of affected fries was filled with transparent viscous ascites with jelly-like mass. Morbidity and mortality was about 60% and 20-25% of the total population, respectively. The BioMerieux Vitek 2 compact system identified the strains as Stenotrophomonas maltophilia . The strains were positive for protease and lipase activity and exhibited alpha haemolytic on sheep blood agar. Our results suggest that S. maltophilia in emerging as a pathogen of C. gariepinus, which is a serious cause for concern.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
