The tapeworm eggs are present in the feces of a person infected with the adult worms, a condition known as taeniasis. [2] [8] Taeniasis, in the strict sense, is a different disease and is due to eating cysts in poorly cooked pork. [1] People who live with someone with pork tapeworm have a greater risk of getting cysticercosis. [8]
Taeniasis is predominantly found in Asia, Africa, and Latin America, particularly on farms in which pigs are exposed to human excrement. At a low level though, it occurs everywhere where beef and pork are eaten, even in countries with strict sanitation policies such as the United States .
Eucestoda, commonly referred to as tapeworms, is the larger of the two subclasses of flatworms in the class Cestoda (the other subclass being Cestodaria). Larvae have six posterior hooks on the scolex (head), in contrast to the ten-hooked Cestodaria .
The tapeworm passes into sticklebacks through its first intermediate hosts, cyclopoid copepods, when these are eaten by the fish. The parasite matures into its third larval stage, the plerocercoid, in the abdomen of the stickleback. Infected sticklebacks are afterwards consumed by fish-eating birds, which serve as the tapeworm's definitive host.
Taenia crassiceps is a tapeworm in the family Taeniidae. It is a parasitic organism whose adult form infects the intestine of carnivores, like canids. It is related to Taenia solium, the pork tapeworm, and to Taenia saginata, the beef tapeworm. It is commonly found in the Northern Hemisphere, especially throughout Canada and the northern United ...
Diphyllobothrium is a genus of tapeworms which can cause diphyllobothriasis in humans through consumption of raw or undercooked fish. The principal species causing diphyllobothriasis is D. latum, known as the broad or fish tapeworm, or broad fish tapeworm. D. latum is a pseudophyllid cestode that infects fish and mammals.
Tapeworms are parasites that live in the bodies of their hosts including humans. A 38-year-old man from China was one such host -- recently having a 20-foot-long version of the parasite removed ...
The definitive hosts for these Taenia species are canids. The adult tapeworms live in the intestines of animals like dogs, foxes, and coyotes. Intermediate hosts such as rabbits, goats, sheep, horses, cattle and sometimes humans get the disease by inadvertently ingesting tapeworm eggs (gravid proglottids) that have been passed in the feces of an infected canid.
