Mesocestoides litteratus (Batsch, 1786) (Cestoda: Cyclophyllidea: Mesocestoididae) from the red fox: Morphological and 18S rDNA characterization of European isolates

2006

Mesocestoides litteratus (Batsch, 1786) (Cestoda: Cyclophyllidea: Mesocestoidae) is a common parasite of the red fox (Vulpes vulpes) and other carnivores across Europe. There has been considerable debate as to the validity of M. litteratus and other closely related, often sympatric species of Mesocestoides. We examine isolates of M. litteratus from red foxes in the Czech Republic, Slovakia and Spain both morphometrically and by characterization of 18S rDNA. Morphometric ranges of all isolates confirmed their identity as M. litteratus and were usually within the range published formerly. The sequences of 18S rDNA of one or two isolates from each country were analysed. The sequences were the same and distinct from all published Mesocestoides 18S sequences with the exception of tetrathyridia from a lizard in the Czech Republic, which was identical to those of M. litteratus.
