Ticks on small mammals at two localities in southern Saskatchewan, Canada and the detection of<i>Rickettsia peacockii</i>(Rickettsiaceae) in<i>Dermacentor andersoni</i>(Acari: Ixodidae) nymphs
Bibliographic record
Abstract
Abstract Seventeen Myodes gapperi (Vigors) (Rodentia: Cricetidae), 13 Peromyscus maniculatus (Wagner) (Rodentia: Cricetidae), 12 Microtus pennsylvanicus (Ord) (Rodentia: Cricetidae), four Zapus princeps Allen (Rodentia: Cricetidae), three Ictidomys tridecemlineatus (Mitchill) (Rodentia: Sciuridae), and eight shrews (Soricomorpha: Soricidae) collected at Blackstrap Lake (BL), and 48 P. maniculatus , 15 Z. princeps, 15 M. pennsylvanicus , and one Sorex monticolus Merriam (Soricomorpha: Soricidae) collected at Saskatchewan Landing Provincial Park (SLPP), in southern Saskatchewan, Canada were examined for ticks. Although no adult ticks were detected on small mammals at either locality, Dermacentor variabilis (Say) (Acari: Ixodidae) larvae ( n =144) and nymphs ( n =7) were found on four species of small mammal at BL. At SLPP, both D. variabilis larvae ( n =71) and nymphs ( n =6), and Dermacentor andersoni Stiles (Acari: Ixodidae) nymphs ( n =9) were collected from small mammals. Both tick species were present on P. maniculatus and M. pennsylvanicus at SLPP, indicating an overlap in their host range and, hence, the potential for transmission of microorganisms between tick species at sites where they coexist. However, the results of polymerase chain reaction assays used to detect bacteria of the genus Rickettsia da Rocha-Lima (Rickettsiaceae) in ticks, revealed that R. peacockii Niebylski et al . only occurred in nymphs of D. andersoni , whereas no Rickettsia were present in the larvae and nymphs of D. variabilis .

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.
