Comparative studies on the mitochondrial nad1 gene sequences between Contracaecum ogmorhini and Contracaecum margolisi
Bibliographic record
Abstract
Nucleotide difference in a portion of the mitochondrial NADH dehydrogenase subunit 1 (nad1) was studied among three populations of C.ogmorhini and C.margolisi from different otariid hosts and geographical, namely, one C.ogmorhini population from Arctocephalus pusillus pusillus (CoAPP) from South Africa, another from Arctocephalus pusillus doriferus (CoAPD) from Australia, and one C.margolisi population from Zalophus californianus (CoZC) from Pacific Canada. A nad1 fragment of approximately 500 bp in length was amplified from individual nematodes by PCR using ()~(33)P-endlabelled primers, analysed by single-strand conformation polymorphism (SSCP), and samples displaying variable SSCP profiles were subjected to sequencing. The results showed that the nucleotide similarity between CoZC and CoAPP/CoAPD was lower than that between CoAPP and CoAPD. Two genetic markers were defined for the differentiation between CoZC and CoAPP/CoAPD. The genetic analysis also confirmed that C.margolisi from the northern hemisphere represents a new species which differs from two populations of C.ogmorhini from the southern hemisphere.

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.
