Are vertebrates actually the only taxonmic group that are hosts for adult tapeworms? --Mperkins 05:04, 12 Dec 2003 (UTC)
this site (http://www.medic8.com/healthguide/articles/tapeworm.html) says that tape worms can affect the eyes, brain and muscles aswell. can someone who knows more about them than me verify this? --hamilt0n 01:04, 25 Nov 2004 (UTC)

Leading genus section
Much of this information is wrong. Even if ite were correct, it wouldn't belong in this article, and should be put in Taenia instead. I've bolded some of the things I know are wrong for sure and put the reason in parentheses.
- In man, the great source of tapeworm is measly pork, eaten uncooked or but partly cooked. The pork tapeworm, Tænia solium, is more common in Europe than in North America. Linnaeus named it solium because it is generally found alone in an infected patient. The farther from the head, the larger is the proglottid (detachable segment). Each proglottid is hermaphroditic and may produce ova ("eggs") when mature.
"Tænia saginata, the beef tapeworm, is common all over the world. Cattle are the intermediary hosts; it is transmitted through imperfectly cooked veal or beef. Its length is about 12 to 25 feet (4 to 8 meters) in its adult stage, which often occurs in man.
- The dog tapeworm, Tænia echinococcus (echinococcus is a genus), seldom exceeds 1/4-inch (0.635 cm) in length. Usually, its length is about 4 or 5 mm. It has only four segments, including the head. The final segment, when sexually mature, equals in length the three anterior ones, and contains as many as 5000 eggs. Man may serve as the intermediary host and become infected with hydatid cysts (cysticerci). In its larval condition, it is, perhaps, more fatally injurious to man than all of the other entozoa put together.
- Tænia nana (this actually goes in the genus Hymenolepis) is frequently found in man in Egypt and Sicily. It is the smallest tapeworm to be found in man in its adult stage. Tænia cucumerina infests the dog and the cat; the flea is host to its larva or cysticercus.
- The word tænia is from the Latin, tænia, Greek, tainia, "a ribbon." Some generic words have been created that apply to tapeworms.
- Tenia - Same as Tænia.
- Tenioid - Resembling a tenia, or tapeworm.
- Tænicide, tæniacide, tenicide - Any substance which kills tapeworms.
- Tænifuge, tenifuge - Any substance used to expel tapeworms from the body.
- Tenifugal - Expelling tapeworms.
- Tæniasis, teniasis - The presence of tapeworms in the body.
- Interestingly, in an allied genus, a tapeworm Bothriocephalus latus (Diphyllobothrium latum (D. latum is a pseudophyllid, not a cyclophyllid. They're not closely related at all.) is sometimes 25 feet (8 meters) long, nearly an inch (2.540 cm) broad, and may have 4000 joints (segments, proglottids). The plerocercoid or infective stage is harbored in fish and probably in a mollusk. It may be found (somewhat smaller) in the dog and the cat. It is said to be the largest tapeworm that lives in man.
May 2nd, 2005 @ 05:07 GMT--- All of the information that was submitted in Leading genus was gleaned from a number of reference books. Those books were compiled in the United states from about 1900 to about 1980, so the terminology and the taxonomy may have changed over time. One book is an old medical dictionary, another book is a regular dictionary, etc.
I'm sorry that things turned out to be incorrect. 05:14 GMT.
HECTOPASCAL
Names of things are changed to satisfy whims (at times). The standard unit of atmospheric pressure was the millibar for most of the 20th century, but it is now the hectopascal. The okra plant had been in the genus Hibiscus for a long time, but is now in another genus called Abelmoschus.
- May 4th, 2005 at 10:02 GMT (Added blurb) While I had accepted the term Hibiscus esculentus as being the "right" scientific term for the okra plant, other people had said: WOE IS ME!
- They went ahead and re-named the okra plant the Abelmoschus esculentus because that is "right", not "wrong."

- 11:00 GMT or Z or UCT (Added) New, and I knew. 11:03 GMT or Z or UCT
The words in Leading genus had been "correct" when they were written down, but they are now "incorrect" words.
Things are being shifted and re-named.
As for me, I'd rather say millibar than hectopascal.

KILOHERTZ
For most of the 20th century, people spoke of kilocycles, but that word has been tossed away because a need to honor Mr. Hertz arose.
As for me, I'd rather say "kilocycle" than "kilohertz."
Scientific terms are subject to being changed from time to time, so that fact makes it risky for the contributors to Wikipedia when submitting blurbs into certain articles.
I had taken the words Leading genus directly from a tome.
Basically, I had simply read the material and strung together the information. The medical dictionary still says that the dog tapeworm is Tænia echinococcus, of course. It was written prior to World War Two, though.
While "kilohertz" had once been completely unknown, today it is the cat's meow.
What hath God wrought? May 2nd, 2005 at 13:45 GMT.
- (May 3rd, 2005 addition) Because of the creation of the Internet, the change away from cycle to hertz has produced billions of speakers who say new words such as "megahertz" and "gigahertz" in place of the old, reliable words "megacycle" and "gigacycle."
Advertisements by personal computer manufacturers describe a "2.0 GHz" CPU, (etc.). The need to honor Mr. Hertz has generated "kilohertz," "megahertz," and "gigahertz" as replacements for the old, reliable "kilocycle," "megacycle," and "gigacycle."
I wonder if Mr. Hertz is turning over in his grave at the thought of people in every hamlet on the globe speaking his name.
Some day in the future the "bicycle" may become called the "bihertz" and the "tricycle" may become the "trihertz." A three-years old child may be described as "peddling his trihertz."

AFRICAN-AMERICAN
Human beings have been re-named, too. The political world has seen the creation of a host of "African-Americans" by those other people who wished to concoct new terms.
"African-Americans" did not exist 50 years ago but they are ubiquitous, today.
May 2nd, 2005 23:59 Z
- 05/05/05 (my last comment) "Those other people who wished to concoct new terms" includes the Presidents of the United states. President Kennedy changed "colored" people into "Blacks" in 1961 soon after he was sworn in as President. "African-American" is a new term which was invented about the 1970s. After the invention of "African-Americans," there were two new terms for President Ronald Reagan to moan and groan over in the 1980s.
- In the 1990s, Congressman Canady of Florida composed "The Civil Rights Act of 1996" which was meant to kill the earlier "Civil Rights Acts" (1957, 1960, 1964, 1968 "laws" or supposed "laws"). He appears to have reasoned that "Blacks" were dominating "Whites" ("Whites" is yet another newly-invented term).
- Soon after he was elected in 2000, President George ("Bushie") Bush laid the groundwork for his re-election in 2004 by giving a speech in which he cited "duh African-American experience." He would not have been able to cite the sad experiences of Negroes because thousands of Negroes have been lynched in the United States.
- The purpose of the new term "African-American" is to serve the political aims of leaders such as U. S. Presidents ("Bill") Clinton and ("Bushie") Bush. ("Ron") Reagan benefitted enormously from the inventions, particularly from "Blacks" and "African-Americans."
- They created rhetoric.
- Where is Congressman Canady, now? Is he still moaning and groaning over the (supposed) "fact" that (supposed) "African-Americans" (actually, they're still slaves) are rich people who "is got all of duh money" (as people said in the 1980s). Is he in the company of Adolph Hitler? ("Ron") Reagan may be snuggled up next to Der Fuhrer.
