Ultrastructural morphology suggesting a new hypothesis for development of microsporidians seen in <i>Loma salmonae</i> infecting the gills of rainbow and brook trout
Bibliographic record
Abstract
In two variants of Loma salmonae that have specificity for rainbow trout Oncorhynchus mykiss(OA variant) and specificity to brook trout Salvelinus fontinalis(SV variant), the parasitophorous vacuole forms at the onset of sporogony. In the OA variant the merogonial stage is bound by a single plasma membrane in direct contact with host cytoplasm. The parasitophorous vacuole formation is initiated by the host cell surrounding the merogonial stages with endoplasmic reticulum (ER) as occurs in autophagy. Of the two host ER membranes surrounding the parasite, one remains in close association with the plasma membrane of the meront, while the other forms the limiting membrane of the vacuole. The sporogonial stage is bounded by two closely apposed membranes, giving the appearance of a thick electron dense plasmalemma. The observations from this study support the novel hypothesis that this microsporidian uses the intracellular process of autophagy to aid formation of a parasitophorous vacuole. The morphology of the SV‐variant is consistent with that of the OA‐variant suggesting that it uses the same mechanism for development.

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.
