Fatal enterocolitis in harbour seals ( <i>Phoca vitulina</i> ) caused by infection with <i>Eimeria phocae</i>
Bibliographic record
Abstract
Coccidiosis due to Eimeria phocae infection has been described in harbour seals (Phoca vitulina) from the western Atlantic population, but not in any detail in seals from the eastern Atlantic population. This paper describes fatal enterocolitis due to E phocae infection in three juvenile harbour seals at a rehabilitation centre in the Netherlands in July 2003. The clinical signs were lethargy, bloody faeces, and intermittent convulsions and muscle tremors just before they died; the nervous signs resembled those of nervous coccidiosis in calves. The main pathological finding was severe, diffuse, haemorrhagic enterocolitis; there were diffuse inflammatory changes in the lamina propria of the jejunal, ileal, caecal and colonic mucosa that were associated with the presence of the sexual stages and oocysts of a coccidian species identified as E phocae. A retrospective microscopical examination of intestinal tissues from 113 harbour seals that had died between 1999 and 2004 revealed one seal that was positive for E phocae.

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.
