摘要: Abstract: Antibodies to morbilliviruses have been documented in free-ranging pinnipeds throughout populations the Atlantic and Arctic Oceans, but not from Pacific Ocean. As a symbolic geographic barrier between exposed naive populations, captive phocid population North America had undocumented serologic status. In this study, canine distemper virus (CDV) serum neutralization assays were used assess prevalence of antibodies with participation 25 U.S. institutions grey seals (Halichoerus grypus, n = 6) harbor (Phoca vitulina, 108). Historic environmental risk factors associated epidemiology collected by survey. Based on virus, exposure was 25.5%, 28 (grey, 2; harbor, 26) demonstrating antibody titers ≥1:16, positive ranged 1:4 1:1,536. By survey analysis, strong associations ...
