Taenia pisiformis is a tapeworm that mainly affects dogs and foxes, and very rarely also cats. Rabbits and rodents act as intermediate hosts. The adult worm is 30 to 150 cm long and about 5 mm wide. The rostellum of the Scolex has two rows of hooks with large (200–295 µm) and small (130–180 µm) hooks.
The proglottids are trapezoidal with simple, clearly protruding genital pores, which are arranged at the edge and irregularly. The uterus has a relatively long central section from which 8 to 14 pairs of sloping side branches branch off.
The intermediate hosts are infected by ingestion of the oncospheres . In the intermediate host, the pea-sized fins ( Cysticercus pisiformis ) develop , which are mostly located in the liver or the mesentery and can be clustered together to form grape-shaped structures in the event of severe infestation.
