Tapeworm (cestoda)
Longest Tapeworm
6 Types
By: Jordan Ledford and Isaias Seibert
The longest tapeworm ever removed from a human came out of Sally Mae Wallace on September 05, 1991. In all, doctors pulled 37 feet of tapeworm out of Sally Mae Wallace's body through her mouth. The world's longest parasite is the tapeworm which can grow up to 120 feet long in whales.
Animals can become infected with these parasites when grazing in pastures or drinking contaminated water. Eating undercooked meat from infected animals is the main cause of tapeworm infection in humans.
Symptoms: (However, often having tapeworms does not cause symptoms. The only sign of tapeworm infection may be segments of the worms, possibly moving, in a bowel movement.)
Abdominal pain
Hunger or loss of appetite
Weight loss
Vitamin and mineral deficiencies

Beef tapeworm (Taenia saginata): comes from cows; can grow up to 25 feet long
Pork tapeworm (Taenia solium): comes from pork; rare in North America but common in South America (including Mexico), Eastern Europe, India, China, and Southeast Asia. Can also be contracted by drinking contaminated food and water, as well as by hand-to-mouth contact after touching something that contains the tapeworm cysts; can grow up to 21 feet long.
Fish tapeworm (Diphyllobothrium latum): comes from fish, and is found in Europe, Japan, North and South America, as well as in certain parts of Africa; can grow up to 25 feet long.
Rodent tapeworm (Hymenolepis nana): comes from fleas, beetles, and cockroach; can grow up to 24 inches long.
Dog tapeworm (Dipylidium caninum): comes from fleas and louse on dogs; most common in children, and is contracted when they accidentally ingest infected flea or louse. It can grow up to 24 inches.
Dwarf tapeworm (Hymenolepis nana): comes from other humans; contracted by the ingestion of food contaminated with feces. It is the smallest of all the worms, and can grow up to 12 inches.
Antihelminthics: Prescribed to eliminate the tapeworm infection; usually, segments of tapeworm start to be shed in the feces within 48 hours of taking these medications.

Laxative: After a round of antihelminthics, your doctor may prescribe a gentle laxative to help purge segments of killed tapeworm from the intestine.

Carl Linnaeus, a Swedish physician and botanist, discovered tapeworms in humans in the year 1758. He is also considered the "Father of Taxonomy," or classification of living species into categories. He helped to identify several other species.
