PARASITES 



suis. Cobbold. See Cystuercus tenia so/it, Leuckart. 

 — Cysticercus taeniae bothrioplitis, Piana. This is 

 bund in the snails Helix carthusianella , Draparnaud, 

 ! ind Helix maculosa, the mature form occurring in the 

 lomestic fowl. — Cysticercus taeniae cesticillus. 

 ioeze-Molin. Syn., Cysticercus tania infundibuli- 

 r'ormis, Goeze. This is found in the house-fly. The 

 idult [Tania cesticillus, Molin, q. v.) is found in the 

 ntestine of the domestic fowl. According to Grassi 

 ind Rovelli the earth-worm Allobophora faetida, 

 lisen. is its intermediate host. — Cysticercus taeniae 

 rassicollis, Rudolphi. This is found in the liver 

 f various rats and mice and is remarkable for the 

 longated form and the smallness of the bladder in 

 rhich it is coiled up. Von Siebold demonstrated 

 the relation of this finn to Tania crassicollis, 

 tudolphi, of the cat. — Cysticercus taeniae cucum- 

 rinae. Bloch. See Cysticercus tenia elliptica ; Batsch. 

 Cysticercus taeniae cuneatae, von Linstow. Occurs 

 i the worm, Allobophora fa-tida, Eisen, and the adult 

 l domestic fowls. — Cysticercus taeniae diminutae, 

 ludolphi. This is found in the orthopterous insect 

 Inisolabis annulipes, Lucas ; and the beetles Akis 

 . Lair, and Scaurus striatus, Fabr. , also in the 

 leal-moth, Asopia farinalis, L. — Cysticercus taeniae 

 llipticae, Batsch. Syn. , Cysticercus tenia cucumeri- 

 a, Bloch. This is found in the fleas (Pulex irritans, L. 

 nd Pulex serraticeps, Gervais) and the dog-louse 

 Trichodectes cam's, DeGeer). — Cysticercus taeniae 

 Tacilis, Rudolphi. This is found in the perch 

 Perca fluviatilis) and by Thos. Scott in the ostracod 

 rustacean Candona rostrata, which Blanchard holds 

 i ) be the intermediate host of Tania gracilis, of the 

 uck. Cysticercus taeniae infundibuliformis, 

 ioeze. See C. tania cesticillus, Molin-Goeze. — Cys- 

 icercus taeniae krabbei, Moniez, occurs in the rein- 

 rvus tarandus, Linne) , the mature form being 

 ound in the dog. — Cysticercus taeniae marginatae, 

 jatsch-Diesing. Syn., Cysticercus clavatus, Cysti- 

 cercus coprinus, Cysticercus globosa, Cysticercus lineata, 

 us tenuicollis, Diesing, Cysticercus phacochari 

 rthiopici, Cobbold, Cysticercus visceralis, Cysticercus 

 \vis, Cobbold. This is the larva of Tania marginata, 

 >atsch ; and is found in the peritoneum and sometimes 

 p the muscles, liver, lungs, and heart of the sheep, 

 oat, ox, camel , reindeer, and pig, and it seems, as the 

 • esult of the researches of Eschricht and others, occa- 

 ionally to occur in monkeys and man. It rarely pro- 

 nous effects, although at times it grows to the 

 ize of a child's head. The size and occurrence have per- 

 j aps led to its being confused and ranked with Echino- 

 ■ xcus, which has led to error, even as regards its 

 uman pathology, it having as a consequence been 

 eckoned among human parasites, especially under the 

 tie, Cysticercus visceralis. — Cysticercus taeniae 

 aicrostomae, Dujardin. Sja.,Scolex decipiens, Dies- 

 ! ig. This occurs in the orthopterous insect Anisolabis 

 \nnulipes, Lucas ; also in the beetle Tenebrio molitor, 

 abricius. The mature form occurs in rats and mice. — 

 Cysticercus taeniae proglottidae, Davaine, occurs in 

 ' le snails Limax agrestis, Linne , and Li max variegatus, 

 )raparnaud. The mature form is found in the domestic 

 >wL — Cysticercus taeniae saginatae, Goeze-Leuck- 

 rt. Syn., Cysticercus bovis, Goeze, Cysticercus medio- 

 ' inellata, Davaine. Leuckart was the first (1861) to 

 how the relation of this finn to the tenia of the ox, 

 i which animal it often occurs in great numbers, 

 specially in Abyssinia. Russia, and the regions about 

 ^e Mediterranean. The distribution in the tissues 

 nd organs varies. The peritoneum and lymphatic 

 pparatus are rarely free from them ; the kidneys, lungs,

and liver contain relatively few ; the muscles especially 

 contain great numbers ; all other tissues and organs 

 may be infected. In the examination of beeves the 

 finns should especially be looked for in the masseteric 

 region, the internal and external pterygoids, heart and 

 tongue. Owing to the presence of calcareous par- 

 ticles, they assume a white color upon drying, which 

 allows their presence to be made out, e.g., in dried 

 beef; soaking will again render them invisible. E. 

 Gavoy asserts that it has not been proved that the 

 finns of Tania saginata do not exist in man. — Cysti- 

 cercus taeniae serratae, Zeder, 

 Goeze. Syn., Cysticercus pisi- Jjiltiflifc l »t 

 formis, Goeze, Cysticercus elon- 

 gatus, Leuckart, Monostoma 

 leporis, Kuhn. This finn is the 

 most common parasite in the 

 peritoneum of the rabbit. It 

 traverses the liver and, reach- 

 ing the peritoneum, excites the 

 formation of a cyst, which be- 

 comes full of fluid, and about 

 the size of a pea. It occurs in 

 such numbers as to resemble 

 clusters of grapes. The white 

 spot on the surface of each 

 bladder locates the invaginated 

 scolex. — Cysticercus taeniae 

 sinuosae, Zeder. Occurs in 

 the crawfish [Astacus fliniat- 

 ilis, Rondelet), and the mature 



form in the domestic duck. — Cysticercus taeniae solii, 

 Leuckart. Syn., Tania hydatigena , Pallas ; Cysticercus 

 cellulosa, Leuckart ; Cysticercus albopunctatus , Cysti- 

 cercus racemosa{us), Zenker ; Cysticercus acanthotrias , 

 Weinland (1858); Cystuercus suis, Cobbold; Cysticercus 

 cam's, Cysticercus multilocularis, Cysticercus pyriformis , 

 Cysticercus Jinna. This is the finn of Tania solium.

KGchenmeister was the first to point out the relation 

 between this bladder-worm and the hook-bearing 

 Tania solium. It causes the disease known as 

 measles and is found in swine, dogs, cats, and man. 

 and occurs in all tissues and organs, producing small 

 tumors which are readily recognized when subcutane- 

 ous ; when in the brain various apoplectiform or epi- 

 leptiform symptoms, paraplegia, violent cephalalgia, 

 vomiting, vertigo, staggers (tournoiement,foumis), con- 

 vulsions, narrowing of the field of vision and deafness 

 may ensue. When in the brain the symptoms resemble 

 those of Tabes dorsalis. No treatment has been found 

 for cerebral cysticercosis ; some cases recover. The 

 enforced inspection of meats is important in this con- 

 nection. — Cysticercus tarandi. See Cysticercus tania 

 krabbei, Moniez. — Cysticercus tenuicollis, Cysti-
