| viral and bacterial serology of free-ranging pacific walrus. | serum or heparinized plasma samples were obtained between 1994 and 1996 from 20 male and 20 female adult free-ranging pacific walrus (odobenus rosmarus divergens) from st. lawrence island and round island, alaska. samples were screened for antibodies to some potentially pathogenic bacteria and viruses. no sample had detectable antibody to brucella spp. three of 40 (8%) had low antibody titers to leptospira interrogans serovars. phocine distemper virus antibodies were not detected. serologic resp ... | 2002 | 11838234 |
| serologic survey for brucella spp., phocid herpesvirus-1, phocid herpesvirus-2, and phocine distemper virus in harbor seals from alaska, 1976-1999. | harbor seals (phoca vitulina richardsi) were captured in the coastal regions of southeast alaska, gulf of alaska, prince william sound (pws), and kodiak island during 1976-1999. blood was collected from 286 seals. sera were tested for evidence of exposure to brucella spp., phocid herpesvirus-1 (phohv-1), phocid herpesvirus-2 (phhv-2), and phocine distemper virus (pdv). antibody prevalence rates were 46% (46/100) for brucella spp., 93% (225/243) for phohv-1, 0% (0/286) for phhv-2, and 1% (2/160) ... | 2006 | 16870851 |
| phocine distemper virus in northern sea otters in the pacific ocean, alaska, usa. | phocine distemper virus (pdv) has caused 2 epidemics in harbor seals in the atlantic ocean but had never been identified in any pacific ocean species. we found that northern sea otters in alaska are infected with pdv, which has created a disease threat to several sympatric and decreasing pacific marine mammals. | 2009 | 19523293 |
| infectious disease and toxicological monitoring of stranded pacific harbor seals (phoca vitulina richardsi) in cook inlet as surrogates for monitoring endangered belugas (delphinapterus leucas). | pacific harbor seals ( phoca vitulina richardsi) and belugas ( delphinapterus leucas ) eat many of the same prey species, occupy the same geographic area, and demonstrate site fidelity in cook inlet, alaska. although most direct research involving the critically endangered belugas is currently prohibited, studying harbor seals may provide important information about this beluga population. in recent years, harbor seal populations in alaska have declined for unknown reasons. as part of its strand ... | 2016 | 27691941 |
| assessment of clinical pathology and pathogen exposure in sea otters (enhydra lutris) bordering the threatened population in alaska. | northern sea otter (enhydra lutris kenyoni) abundance has decreased dramatically over portions of southwest alaska, usa, since the mid-1980s, and this stock is currently listed as threatened under the endangered species act. in contrast, adjacent populations in south central alaska, usa, and russia have been stable to increasing during the same period. sea otters bordering the area classified in the recent decline were live-captured during 2004-2006 at bering island, russia, and the kodiak archi ... | 2011 | 21719822 |
