[Contribution to the knowledge of Taenia crassiceps (Zeder, 1800) Rudolphi, 1810 (Cestoda, Taeniidae) (author's transl)].

The occurrence of Taenia crassiceps in naturally infected dogs is mentioned, and a brief description of the gravid proglottids is given. Oral infection of several rodent species with eggs showed that the field vole (Microtus arvalis) is the most susceptible intermediate host for this tapeworm. The cysticercus often develops in the brain of the rodent and causes disturbances of coordinated movements. Two foxes (Vulpes vulpes) were infected with cysticerci of the strains COLA and GIKS. These strains were originally isolated from two dogs. The foxes passed fertile eggs and proglottids as early as 31 and 32 days respectively after infection.
