Parasitology Research, 94(1), 10-15.0932-0113https://doi.org/10.1007/s00436-004-1164-yhttp://hdl.handle.net/11452/21723Phylogenetic analysis of sequences of the ITS-2 rRNA genes of 20 samples of pseudophyllidean cestodes of the family Diphyllobothriidae (Ligula, Digramma, Diphyllobothrium, and Schistocephalus) from different hosts and geographical regions revealed that: (1) the inclusion of ligulids (previously family Ligulidae) to the Diphyllobothriidae is correct; (2) Schistocephalus appears as the most basal taxon of the Diphyllobothriidae, well separated from Ligula and Digramma, thus supporting the validity of Schistocephalinae Dubinina, 1962; (3) Digramma belonged with samples of Ligula, thus suggesting its invalidity as a genus; and (4) isolates of Ligula, presumably belonging to Ligula intestinalis, are paraphyletic, indicating that this species may represent a complex of separate taxa. Our results indicate the necessity for a taxonomic revision of the family Diphyllobothriidae.eninfo:eu-repo/semantics/closedAccessParasitologyCestodaDigrammaDiphyllobothriidaeDiphyllobothriumLigulaLigula intestinalisLigulidaePseudophyllideaSchistocephalus18S ribosomal DNABothriocephalus-rudolphiLigula-intestinalisHost manipulationPlatyhelminthesInterrelationshipsParasitesEvolutionGenesKeyAnimalsCestodaCestode infectionsDiphyllobothriumDNA, ribosomal spacerFish diseasesFishesMolecular sequence dataPhylogenySequence analysis, DNAArticle0002235358000022-s2.0-4544258027101594115278441ParasitologyCestoda; Proteocephalidae; KhawiaRibosome DNACestodeDNA determinationDNA sequenceGeographic distributionHost parasite interactionNonhumanParasite identificationParasite localizationPhylogenyPriority journalTaxon
