Discovery of a vector for two Elasmobranch Cestode species. It is also vulnerable to the cestode "Alcataenia campylacantha". It can also be an intermediate host for the flea tapeworm cestode "Dipylidium caninum". The adults of all 3,400 cestode species are internal parasites. Taenia solium is the pork tapeworm, a tapeworm belonging to the cyclophyllid cestode family Taeniidae. Reproduction for this parasite is unique because of the hermaphroditic nature of this cestode. Several parasites including a cestode have been identified in this species. The main nerve centre of a cestode is a cerebral ganglion in its scolex. Studies of the intestines have observed the nematode "Tictularia cristata" and the cestode "Hymenolepsis diminuta". Other worms include two nematodes and the cestode "Hymenolepis horrida". "H. nana" is the only cestode capable of completing its lifecycle without an intermediate host. It is a very typical of cestode with striking resemblance to other species of "Raillietina". It is also a common intermediate host of cestode parasites, such as "Schistocephalus solidus". A species of endoparasitic cestode, "Triaenorhina burti" has been described from the species. In general cestode infections are treated with praziquantel and albendazole.
