| Title | IDENTITY OF DIPHYLLOBOTHRIUM SPP. (CESTODA: DIPHYLLOBOTHRIIDAE) FROM SEA LIONS AND PEOPLE ALONG THE PACIFIC COAST OF SOUTH AMERICA. | | Author(s) | Rausch R, Adams AM, Margolis L | | Source | J Parasitol 2009 Nov 5.:1. | | Abstract | Host-specificity evidently is not expressed by various species of the genus 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, D. pacificum and D. arctocephalinum, for which sea lions (Otariidae) are final hosts. The taxonomic status of those cestodes has not been clearly discernible, due to misinterpretation of relationships; complex synonymies have resulted from misidentification(s). Stiles and Hassall in 1899 obtained but did not describe cestodes from the northern fur seal (Otariidae) (Pribilof Islands). That taxon was studied by several investigators, with diverse conclusions. The valid designation is D. pacificum (Nybelin, 1931). In 1937, Johnston and Drummond described separately 2 conspecific cestodes from sea lions near Australia, designated D. arctocephalinum and D. arctocephali, respectively. Both names have been listed incorrectly as synonyms of D. pacificum. The structure and possible function of an organ common to D. pacificum and D. arctocephalinum are discussed. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
