A new species of Parafilaroides (Nematoda: Filaroididae) in three species of fur seals (Carnivora: Otariidae) from the Southern Hemisphere.

Blocks of frozen lungs of 2 Australian fur seals (Arctocephalus pusillus doriferus Wood Jones, 1925), 2 New Zealand fur seals (A. forsteri [Lesson, 1828]), and 1 sub-Antarctic fur seal (A. tropicalis [Gray, 1872]) from 3 different locations (Australia, New Zealand, and South Africa, respectively) were examined and found to contain lung parasites.

Restoration of Parafilaroides (Dougherty, 1946) (Nematoda: Metastrongyloidea) with description of two new species from pinnipeds of eastern central Pacific.

The lungs of a northern elephant seal, Mirounga angustirostris (Gill, 1866), and Pacific harbor seal, Phoca vitulina richardii (Gray, 1864), from the eastern central Pacific, central California coast, were examined for parasites. This represents the first thorough description and identification of Parafilaroides species from northern elephant seals and Pacific harbor seals on the west coast of North America. From this study, 2 new species of Filaroides (Parafilaroides) are described, illustrated, and differentiated by shape of vaginal sphincter, body morphometrics, and spicule shape from the 4 existing, recognized species in the subgenus.

Molecular phylogenetics and diagnosis of Anisakis, Pseudoterranova, and Contracaecum from northern Pacific marine mammals.

Individual specimens of Anisakis, Pseudoterranova, and Contracaecum collected from marine mammals inhabiting northern Pacific waters were used for comparative diagnostic and molecular phylogenetic analyses. Forty-eight new sequences were obtained for this study of 14 Anisakis taxa, 8 Pseudoterranova taxa, 4 Contracaecum taxa, and 4 outgroup species. Partial 28S (LSU) and complete internal transcribed spacer (ITS-1, 5.

Helminth parasites of the southern sea otter Enhydra lutris nereis in central California: abundance, distribution and pathology.

From October 1997 to May 2001, the gastrointestinal tracts from 162 beach-cast southern sea otters Enhydra lutris nereis were examined for helminth parasites and associated lesions. Carcasses were collected opportunistically in central California between Pt. San Pedro and Pt.

First report of a parasitic copepod (Pennella balaenopterae) infestation in a pinniped.

An infestation by the parasitic copepod Pennella balaenopterae was found in a stranded, 8-mo-old, female northern elephant seal (Mirounga angustirostris). Diagnosis was based on the finding of the cephalothoraxes of 14 adult female copepods from three subcutaneous sites. Bacteria cultured from lesion exudate included Arcanobacterium phocae, Escherichia coli, Edwardsiella tarda, an Enterococcus sp.
