Fish-borne, zoonotic cestodes (Diphyllobothrium and relatives) in cold climates: A never-ending story of neglected and (re)-emergent parasites
Fish-borne cestodes capable of infecting humans are represented almost exclusively by so called broad tapeworms, i.e. members of the order Diphyllobothriidea. These large-sized human tapeworms have three host life-cycles, in which teleost fishes (except in the case of Spirometra) play a role of the...

Fish-borne cestodes capable of infecting humans are represented almost exclusively by so called broad tapeworms, i.e. members of the order Diphyllobothriidea. These large-sized human tapeworms have three host life-cycles, in which teleost fishes (except in the case of Spirometra) play a role of the second intermediate hosts and represent a source of human infection. Although the broad fish tapeworms (genera Adenocephalus, Diphyllobothrium and Diplogonoporus) have been recognized as human parasites for a long time, many aspects of their biology and epidemiology, including species composition of individual genera, their clinical relevance and geographical distribution have been noticeably understudied. The overriding obstacle preventing clarification of the diversity, origin and host-associations of diphyllobothriids is the poor state of systematics of the group. Even though diphyllobothriosis itself is not a life-threatening disease, it is considered the most important fish-borne zoonosis caused by a cestode with up to 20 million people estimated to be infected worldwide, with an affinity to colder climates including subarctic and arctic areas of the North and partly South Hemisphere.
