  1. The novel sequences obtained in the present study are highlighted in bold
  2. aSika deer and brown rats are wild animals, and the others are domestic animals
  3. bAbsence of G. duodenalis in goats (Capra hircus) (n = 7), horses (Equus caballus) (n = 18), arctic foxes (Vulpes lagopus) (n = 82), blue foxes (Alopex lagopus) (n = 70) and minks (Neovison vison) (n = 24) in the present study
  4. cAt the tpi locus, 19 G. duodenalis-positive specimens (in italics) were successfully sequenced using general primers and assemblage-specific primers, while the others were only sequenced successfully using assemblage-specific primers
