| parasites and associated pathology observed in pinnipeds stranded along the oregon coast. | forty-two seals and sea lions found dead along the oregon coast were examined for parasites and associated pathology. nematode infections of the lung and/or gastrointestinal tract were the primary cause of death in 5 of 42 animals examined. new distribution records were established for pricetrema zalophi and zalophotrema hepaticum. new host records include z. hepaticum and diphyllobothrium cordatum in the steller's sea lion (eumetopias jubatus); nanophyetus salmincola in the california sea lion ... | 1978 | 567698 |
| characterization of otostrongylus circumlitus from pacific harbor and northern elephant seals. | otostrongylus circumlitus (railliet, 1899) from pacific harbor seals (phoca vitulina richardsi) and northern elephant seals (mirounga angustirostris) were examined using morphological and molecular methods to determine whether northern elephant seals along the central california coast are infected by the same species of otostrongylus as are pacific harbor seals in the same area. fixed nematodes were examined and measured using light microscopy. the polymerase chain reaction (pcr) was used to amp ... | 2001 | 11227905 |
| metastrongyloid nematode (otostrongylus circumlitus) infection in a stranded california sea lion (zalophus californianus)--a new host-parasite association. | a stranded yearling male california sea lion was admitted to a rehabilitation center june 2003. on presentation, the sea lion was emaciated and had diarrhea and neutrophilia. two weeks later, the animal became anorexic, blood and mucus were observed around the oral cavity, and corneal opacity was noted in the right eye. hematology results at that time included leukocytosis consisting of neutrophilia with a left shift, anemia, and thrombocytopenia. despite supportive care, the sea lion died. on p ... | 2005 | 16244070 |
