In Reply to: Finally, pictures of a cestode (tapeworm) from an iguana posted by Marie Eguro on February 07, 2000 at 20:12:17:

Marie ...what a great addition to Akira's site. Since tapeworms are VERY prevelant in herbivorus animals....namely cattle,horses,sheep...getting cestodes from vegetation. Organic and "homegrown" greens and veggies would really really need to be washed thoroughly prior to feeding our igs. Dogs fecal matter on vegetation not washed thoroughly is another way of transporting tapeworm I would think. Here's a little what the CDC had to say about tapeworm ( there were I think 6-7 different types listed...this is just one) & vegetation...

Life cycle of Taenia saginata
Humans are the only definitive hosts for Taenia saginata. The adult tapeworms (length: usually 5 m or less, but up to 25 m) reside in the small intestine, where they attach by their scolex. They produce proglottids (each worm has 1,000 to 2,000 proglottids), which mature, become gravid, detach from the tapeworm, and migrate to the anus or are passed in the stool (approximately 6 per day). The eggs contained in the gravid proglottids (80,000 to 100,000 eggs per proglottid) are released after the proglottid becomes free and are passed with the feces. The eggs can survive for months to years in the environment. Cattle and other herbivores become infected by ingesting vegetation contaminated with eggs (or proglottids). In the animal's intestine, the eggs release the oncosphere, which evaginates, invades the intestinal wall and migrates to the striated muscles, where its develops into a cysticercus. The cysticercus can survive for several years in the animal. Humans become infected by ingesting raw or undercooked infected meat. In the human intestine, the cysticercus develops over 2 months into an adult tapeworm, which can survive for more than 30 years.
