“…Diphyllobothrium klebanovskii Kuratov et Posokhov, 1988, was isolated from the lower Amur River basin in the Russian Far East (72). Synonymy with D. nihonkaiense has been confirmed by molecular data (12).…”

“…In most analyses, D. pacificum and/or D. stemmacephalum (type species of the genus) represent the most basal taxa of the genus (12,22,81,150). Diphyllobothrium nihonkaiense is the basal taxon to the clade formed by D. latum, D. dendriticum, and D. ditremum, which also contains members of the genera Ligula and Digramma, the adults of which are parasites of fish-eating birds (44).…”

“…Such a topology of the cladogram implies that the genus Diphyllobothrium represents a para-or polyphyletic assemblage of taxa that do not form a monophyletic group (12,22,169). Molecular data also indicate that Diplogonoporus balanopterae (Lönnberg, 1891) [synonym, Diplogonoporus grandis (Blanchard, 1894)] is a species of Diphyllobothrium with doubled genitalia in a segment (11,12). This human-infecting parasite is therefore included in our review.…”

“…The parasite is widespread in all major river basins east of the Urals, including those of Lena, Kolyma, and Indigirka (151). The coastal areas of the Okhotsk Sea, where human prevalence ranges from 1.0 to 3.3% (91), are also endemic foci (12).…”

SUMMARYTapeworms (Cestoda) continue to be an important cause of morbidity in humans worldwide. Diphyllobothriosis, a human disease caused by tapeworms of the genusDiphyllobothrium, is the most important fish-borne zoonosis caused by a cestode parasite. Up to 20 million humans are estimated to be infected worldwide. Besides humans, definitive hosts ofDiphyllobothriuminclude piscivorous birds and mammals, which represent a significant zoonotic reservoir. The second intermediate hosts include both freshwater and marine fish, especially anadromous species such as salmonids. The zoonosis occurs most commonly in countries where the consumption of raw or marinated fish is a frequent practice. Due to the increasing popularity of dishes utilizing uncooked fish, numerous cases of human infections have appeared recently, even in the most developed countries. As many as 14 valid species ofDiphyllobothriumcan cause human diphyllobothriosis, withD. latumandD. nihonkaiensebeing the most important pathogens. In this paper, all taxa from humans reported are reviewed, with brief information on their life history and their current distribution. Data on diagnostics, epidemiology, clinical relevance, and control of the disease are also summarized. The importance of reliable identification of human-infecting species with molecular tools (sequences of mitochondrial genes) as well as the necessity of epidemiological studies aimed at determining the sources of infections are pointed out.

“…A custom primer pair was designed to amplify a 349-bp region of the Diphyllobothrium cytochrome c oxidase subunit 1 (cox1) gene based on publicly available sequences (forward primer, 5=-TGCACTCTCTACACAGCGTTT-3=; reverse primer, 5=-ATGCCCCCACACAACACTAC-3=). This specific region was selected because it contained residues that discriminate between D. nihonkaiense and Diphyllobothrium klebanovskii (12). The PCR was performed using the AccuPrime Pfx DNA polymerase kit (Invitrogen, Carlsbad, CA) with the following cycling conditions: 95°C for 2 min followed by 35 cycles at 95°C for 15 s, 55°C for 30 s, and 68°C for 90 s, and a final extension at 68°C for 2 min.…”
