Murai, É.: Taeniid species in Hungary (Cestoda: Taeniidae). II. Larval stages of taeniids parasitizing rodents and lagomorphs
Characterization of the larval Taenia tenuicollis Cysticercus talpae were found in the liver of 112 specimens representing 7 species of intermediate hosts (about 150 preparations were specially made). The shape of the cyst is oval to globular (Fig. 6), usually situated on the surface of the liver (at massive infestation also in the deeper layers). The cyst is translucent, with the Cysticercus freely situated in it. Diameter of the host-cysts varied from 1 to 3 mm, the oval-shaped cysticerci varied in size from 0.8 to 2.0 mm. The host-cyst contains one Cysticercus only, which has an invaginated scolex. Young larvae contain few, but older larvae posses a larger number of calcareous bodies. Diameter of the scolex is 0.3 mm, that of the rostellum vary from 0.075 to 0.082 mm, that of the suckers from 0.120 to 0.140 mm. The rostellum is arranged in two rows of hooks which are very similar and only slightly different in size. The number of hook vary from 43 to 58. The length of the large hooks vary from 0.020 to 0.023 mm (sometimes 0.025 mm), those of the small ones from 0.018 to 0.020 mm. The base of the hooks is 1-2 jum shorter than its length (Figs. 17-19).
