Sentinel Surveillance for Zoonotic Parasites in Companion Animals in Indigenous Communities of Saskatchewan
Bibliographic record
Abstract
Indigenous communities may have increased risk of exposure to zoonotic parasites, including Echinococcus granulosus, Toxocara canis, Toxoplasma gondii, Diphyllobothrium spp., and Giardia duodenalis, for which dogs may serve as sentinels for or sources of human infection. Canid fecal samples were collected from dogs and the environment in five indigenous communities across Saskatchewan and Alberta (N = 58, 62, 43, 66, and 25). Parasites in individual fecal samples were quantified using fecal flotation and a commercial immunofluorescent antibody test for Giardia and Cryptosporidium. Overall, the prevalence of canine intestinal parasitic infection was 20-71%, which is 5-16 times higher in indigenous communities than a nearby urban center in Saskatchewan. The overall prevalences of T. canis, Diphyllobothrium, and taeniid eggs in dog feces were, respectively, 11.8%, 4.9%, and 1.2% in our study compared with 0-0.2% in urban dogs. Giardia cysts present in 21% of samples were identified as zoonotic genotype Assemblage A.

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.
