Helminth parasites and zoonotic risk associated with urban coyotes (<i>Canis latrans</i>) in Alberta, Canada
Bibliographic record
Abstract
Coyotes (Canis latrans) are resilient, adaptable, cosmopolitan omnivores that are increasingly prevalent in urban environments, where they interact with both humans and domestic dogs. Coyotes potentially transmit zoonotic parasites, including the tapeworm Echinococcus multilocularis, which appears to be increasing in prevalence in western North America. In this study, we analysed the carcasses of 23 urban coyotes in Edmonton, Alberta, Canada. Focusing primarily on the helminth community, we recovered three tapeworm species (E. multilocularis, Taenia pisiformis, T. serialis), four nematodes (Toxascaris leonina, Uncinaria stenocephala, Capillaria sp., Physaloptera sp.), and two trematodes (Alaria arisaemoides and A. americana). Compared to previous studies of urban coyotes conducted in North America, we report one of the highest levels of E. multilocularis infection in North America: 65.2% infection prevalence. These results amplify concerns expressed by others about the increasing prevalence of this zoonotic parasite and the role coyotes may play in parasite transmission. More research is needed to better understand how various ecological factors, urbanization and wildlife management practices influence the transmission of potentially zoonotic parasites such as E. multilocularis.

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.
