| epizootiology of morbillivirus infection in north american harbor seals (phoca vitulina) and gray seals (halichoerus grypus). | a longitudinal study of morbillivirus infection among harbor (phoca vitulina) and gray (halichoerus grypus) seals on the atlantic coast of north america was carried out between 1980 and 1994. serology also was carried out on harbor seals from the pacific northwest coast collected in 1992 and 1993. the prevalence of morbillivirus neutralizing antibodies was significantly (p < 0.0001) higher in gray (73%, n = 296) than in harbor seals (37%, n = 387) from the atlantic. titers were significantly (p ... | 1995 | 8592380 |
| polychlorinated biphenyls (pcbs) and their hydroxylated metabolites (oh-pcbs) in livers of harbor seals (phoca vitulina) from san francisco bay, california and gulf of maine. | bioaccumulation of endocrine disruptors in marine mammals positioned at the top of the food chain is of toxicological concern. livers from four pups and ten adult harbor seals (phoca vitulina) stranded in san francisco bay (sfb) and the gulf of maine (gom) were analyzed for polychlorinated biphenyls (pcbs) and their hydroxylated metabolites (oh-pcbs). we used gc-ecd and gc-nci/ms to investigate the presence of 28 pcbs and 8 oh-pcb metabolites, respectively. sigma(28)pcb concentrations (di- to oc ... | 2009 | 19150735 |
| DETECTION OF CRYPTOSPORIDIUM SP. SEAL IN TWO NEW SEAL SPECIES, PHOCA VITULINA AND CYSTOPHORA CRISTATA AND A NOVEL CRYPTOSPORIDIUM GENOTYPE IN A THIRD SEAL SPECIES, PAGOPHILUS GROENLANDICUS FROM THE GULF OF MAINE. | Abstract Data on the geographic distribution and host-specificity of Cryptosporidium spp. are critical for developing an understanding of likely transmission patterns in nature. During a molecular based survey of fecal samples from 293 terrestrial and aquatic animals in Maine, we detected Cryptosporidium sp. in 11 harbor seals, 1 hooded seal, and 1 harp seal. None of the terrestrial or freshwater mammal fecal samples or bird samples tested positive for Cryptosporidium sp. However, the seque ... | 2011 | 22017467 |
| evaluation of hematologic and biochemical values for convalescing seals from the coast of maine. | marine mammal researchers and veterinarians evaluate the health of individuals and populations by using observed ranges for blood values. the goal of this study was to establish observed ranges for dependent (0-4 week) and weanling (>4 week) harbor seal (phoca vitulina) pups that were admitted for rehabilitation at the marine animal lifeline in portland, maine from 1998-2003 and to record changes in hematologic and biochemical values as they convalesced. blood values, measured both at admission ... | 2009 | 19746855 |
