^aDogs were categorized as autochthonous negative (Autoc⁻) or positive (Autoc⁺) at baseline or as sentinel beagles (all negative at baseline). Cytblo, cytology of blood smears; Cytbcoa, cytology of buffy coat smears; PCR, PCR analysis after extraction of DNA from blood; Pos, positive.

^bn, no. of animals in group.
