Neospora caninum DNA in Coyote Fecal Samples Collected in an Urban Environment
Bibliographic record
Abstract
Definitive hosts of Neospora caninum are species of canids, such as domestic dogs ( Canis lupus familiaris), coyotes ( Canis latrans) and foxes ( Vulpes vulpes), whereas ruminants, such as cattle ( Bos taurus), sheep ( Ovis aries), and deer (Cervidae) serve as intermediate hosts. We investigated the presence of N. caninum in feces of coyotes in Calgary, Alberta, Canada. One hundred coyote fecal samples were collected from five city parks. Following DNA extraction, the presence of N. caninum DNA was determined by using real-time PCR analysis with a primer and probe pair targeting the Nc5 gene. Ten of the 100 samples contained detectable amounts of N. caninum DNA. White-tailed deer ( Odocoileus virginianus) and mule deer ( Odocoileus hemionus) are common in Calgary's city parks, and although we did not examine them for the presence of N. caninum bradyzoites, the presence of N. caninum DNA in coyote fecal samples is indicative that a sylvatic host of N. caninum exists within this urban environment.
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.
