Diphyllobothrium latum

Diphyllobothrium latum. It occurs in Finland, Switzerland, France, Siberia and in the Great Lakes area near the USA and Canada border. The sources of infection are plerocerkoids, a few centimeter long worms-like larvas, parasitizing in freshwater fish. A mature female form is about 2-9 m. long and produces a substantial amount of eggs excreted with faeces. Diphyllobothrium is easily recognizable by microscopic stool examination. This type of tapeworm causes several non-characteristic general symptoms in the alimentary canal. 2% of hosts suffer from megaloblastic anemia caused by a considerable selective assimilation of vitamine B12 by the tapeworm.

Taeniasis (taenia saginata) is the biggest cestodiasis in Europe caused by a custom of eating raw meat and considerable contamination of the environment by sewage.
