Arctic fox, Alopex lagopus ; dog, Canis familiaris. Although the broad fish diphyllobotheium has been recognized as a human parasite for a long time, many aspects of its biology and epidemiology, including the spectrum of hosts causing human infection, clinical relevance, and present distribution, still remain poorly known.

The importance of the disease is emphasized by its current recrudescence in some regions of the most developed countries throughout the world. Z and LC This parasitosis is caused by consumption of poorly cooked fish. DNA extraction can be made diphyllobothium with a commercial kit or with the classic phenol-chloroform method, which seems to yield larger amounts of DNA, especially from small-sized procercoid larvae Brackish-Water and Marine Fish There are very few reliable data on the occurrence of plerocercoids of Diphyllobothrium in brackish-water and marine fish 5 Parasitology as an interpretative tool in archaeology.
