Encephalitozoon pogonae–Associated Systemic Vasculitis in a Central Bearded Dragon (Pogona vitticeps)
Bibliographic record
Abstract
Abstract A 4-yr-old female central bearded dragon ( Pogona vitticeps ) with a history of tenesmus was found dead 1 month after surgical debulking of a palpable caudal coelomic mass. At necropsy, a 2.5-cm-diameter, firm, lobulated, tan–yellow mass was associated with the wall of the pelvic canal and bilateral masses were present in the caudal pharynx (0.6 and 3.0 cm in diameter), the largest of which was soft and dark red. Histologically, the mass within the pelvic canal arose from the coelomic wall and consisted primarily of fibrocollagen with myxoid to cystic regions, and mixed inflammatory infiltrates. Additional findings included granulomatous dermatitis, myositis/cellulitis, coelomitis, encephalitis, and pneumonia. Vasculitis was detected in multiple organs, and in the pharynx resulted in aneurysmal dilation and perivascular hemorrhage leading to masslike lesions. Within all lesions, scattered macrophages contained oval, weakly basophilic, Gram-positive, slightly refractile, 1–2 µm-diameter ovoid organisms consistent with microsporidia. A diagnosis of systemic microsporidiosis characterized by lymphohistiocytic and heterophilic vasculitis with medial hypertrophy and fibrinoid necrosis was made. Using DNA sequencing, the organism was identified as Encephalitozoon pogonae . Encephalitozoon pogonae should be considered a differential diagnosis for vasculitis and aneurysms in bearded dragons.

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.
