Description of a New Species of Myxozoan from Notropis hudsonius in the Great Lakes Region of Canada
Bibliographic record
Abstract
Myxobolus burti n. sp. is described from striated muscle of Notropis hudsonius (Cyprinidae) collected from localities in Lake Superior, Lake Michigan, Lake Huron, Lake St. Claire, Lake Erie, Lake Ontario, and the St. Lawrence River. Myxobolus burti is intracellular, forming thin-walled, cigar-shaped plasmodia within striated muscle cells of the body. It exhibits disporoblastic, oval spores, approximately 10 µm long, 8 µm wide, and 6 µm thick, with a length-to-width ratio of 1.3 ∶ 1. They resemble most closely those of Myxobolus bellus Kudo, 1934, and Myxobolus mutabilis Kudo, 1934, but have polar capsules unequal in length (5.3 vs. 4.7 µm) and oblique filament coils. The new parasite was not encountered in routine examination of other small-bodied fishes at collection locations and thus looks to be specific to N. hudsonius. A comparative plate of similar species encountered during surveys of these fishes in the northeast is presented to contrast the uniqueness of the new species.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
