In some species, such as the spined loach (Cobitis taenia) of Eurasia, there is also a short, movable spine near each eye.
The tapeworm taenia solium is a parasite that grows to between 3-7m in the human intestine.
Given that taenia solium is shared between animals and humans there is a strong need for sharing information across the agricultural, livestock and human health sectors.
Taenia, genus of tapeworms parasitic in mammals.
The tapeworm species Diphyllobothrium latum or one of several different species in the genus Taenia, in addition to several other genera, can be infectious.
The common tapeworms are Taenia saginata, found in beef, and T. solium, found in pork.
The pork tapeworm (Taenia solium), for example, alternates between pigs and humans in societies in which improperly cooked pork is eaten.
The more common ones include the following: Taenia saginata, or beef tapeworm, about 4.5 to 6 m (15 to 20 feet) long; Taenia solium, or pork tapeworm, about 2 to 3 m long; and Diphyllobothrium latum, about 9 m long, acquired by the eating of undercooked beef, pork, or fish that harbour larval forms of the worms.
In Europe and the United States the beef tapeworm (Taenia saginata) is common because of the habit of eating undercooked steaks or other beef products.
The pork tapeworm (Taenia solium, or Taeniarhynchus solium), found wherever raw pork is eaten, lives in the human intestine in its adult stage.
The life cycle of the beef tapeworm (Taenia saginata, or Taeniarhynchus saginatis), which occurs worldwide where beef is eaten raw or improperly cooked, is much like that of the pork tapeworm.
