What's the difference between strobila and tapeworm?
Strobila
Definition:
(n.) A form of the larva of certain Discophora in a state of development succeeding the scyphistoma. The body of the strobila becomes elongated, and subdivides transversely into a series of lobate segments which eventually become ephyrae, or young medusae.
(n.) A mature tapeworm.
Example Sentences:

(3) When the oncosphere of H. nana undergoes differentiation and development into the mature tapeworm, the infected mouse first produces anti-oncosphere antibody, followed by anti-cysticercoid, anti-adult scolex and finally anti-strobila (other than scolex region) antibodies of IgG, IgM and IgA isotypes as detected by indirect immunofluorescent antibody test.

(15) All 56 treated individuals remained stool-negative after 60 and 90 d; a partial strobila or segments were recovered from 21 of them (37.5%).
(16) It differs from R. scorzai in number of bothridial loculi, testes per proglottid, and proglottids per strobila; by having quadrate rather than canoe-shaped bothridia; and by parasitizing Potamotrygon magdalenae rather than P. hystrix.
(17) The scolex and remaining strobila survived but were recovered from a more posterior region of the intestine where small worms are attached during development.
(18) At the laboratory they were identified as Taenia saginata strobila with immature, mature and gravid proglottids.
(19) The rostellum, the cerebral ganglia and commissure, and the strobila contained numerous process-free, unipolar and multipolar serotoninlike immunoreactive cells.
(20) The posterior nerves form a subtegumental network in the strobila and the bladder wall.
Tapeworm
Definition:
(n.) Any one of numerous species of cestode worms belonging to Taenia and many allied genera. The body is long, flat, and composed of numerous segments or proglottids varying in shape, those toward the end of the body being much larger and longer than the anterior ones, and containing the fully developed sexual organs. The head is small, destitute of a mouth, but furnished with two or more suckers (which vary greatly in shape in different genera), and sometimes, also, with hooks for adhesion to the walls of the intestines of the animals in which they are parasitic. The larvae (see Cysticercus) live in the flesh of various creatures, and when swallowed by another animal of the right species develop into the mature tapeworm in its intestine. See Illustration in Appendix.
Example Sentences:
(1) The plerocercoid stage of the tapeworm Spirometra mansonoides produces a functional analog of human growth hormone (hGH).
(2) The drug of choice against all kinds of tapeworms is Niclosamide.
(3) Untreated control dogs did not shed tapeworms of either species during a 3-day period of posttreatment fecal collections, but did have tapeworms at the time of necropsy.

(6) Infection in humans or animals by the common tapeworm of dogs and cats (Dipylidium caninum) requires ingestion of the intermediate host, the dog or cat flea containing the larva (cysticercoids) of the agent.
(7) The diphyllobothriid tapeworms are primarily restricted to the northern Canada.
(8) One hundred and seven 4-quinolinehydrazones were synthesized and tested in vivo against the tapeworm Hymenolepis nana.
(9) When the oncosphere of H. nana undergoes differentiation and development into the mature tapeworm, the infected mouse first produces anti-oncosphere antibody, followed by anti-cysticercoid, anti-adult scolex and finally anti-strobila (other than scolex region) antibodies of IgG, IgM and IgA isotypes as detected by indirect immunofluorescent antibody test.
(10) Factor analysis grouped the variables considered into 5 factors: the first was associated with veterinary assistance; the second with the animal's function and the presence of whipworms, hookworms and tapeworms; the third with cohabitation, origin and presence of coccidia; the fourth with the presence of fresh meat (cooked, raw or frozen) in the diet, age and positivity for ascarids; the fifth with sex and the presence of gastroenteric conditions.
(11) H. citelli was also shown to be expelled simultaneously during the rejection phase of H. diminuta in concurrent infections, indicating the susceptibility of the former tapeworm to the rejection mechanism initiated by the latter.
