Host specificity evidently is not expressed by various species of Diphyllobothrium that occur typically in marine mammals, and people become infected occasionally when dietary customs favor ingestion of plerocercoids. This report mainly concerns 2 species, Diphyllobothrium pacificum and Diphyllobothrium arctocephalinum, for which sea lions (Otariidae) are final hosts. The taxonomic status of th...

The present study was performed to compare the mitochondrial genomes between 2 Spirometra tapeworms, Spirometra erinaceieuropaei and Spirometra decipiens (Cestoidea: Diphyllobothriidae), which larval stages are important etiological agents of sparganosis in humans. For each species, the full mitochondrial genome was amplified in 8 overlapping fragments using total genomic DNA purified from a si...

background: the plerocercoid stage of pseudophyllideancestoda infected a wide range of fresh water fish,particularly the members of the cyprinidae family. the parasitespecies are the most common pathogens that have severe effectson fish. objectives: the aim of the present study is todetermine the occurrence and distribution of the plerocercoid ofdiphyllobothriidae in two freshwater fish from no...
