the serological response of the common seal (phoca vitulina) and the grey seal (halichoerus grypus) to phocine distemper virus as measured by a canine distemper virus neutralisation test.the application of a canine distemper virus (cdv) neutralisation test revealed that antibody titres of up to 11,620 were present in the sera of common seals during the epizootic of phocine distemper in british waters. however, during the later stages of the epizootic and afterwards, a surprisingly high proportion of animals were still seronegative. titres of from 90 to 183 were common in diseased animals and were probably indicative of partial immunosuppression. a few animals with proven phocine ...19921594940

morbillivirus infections of seals during the 1988 epidemic in the bay of heligoland: iii. transmission studies of cell culture-propagated phocine distemper virus in harbour seals (phoca vitulina) and a grey seal (halichoerus grypus): clinical, virological and serological results.eight harbour seals (phoca vitulina), two of them seronegative, six seropositive against pdv and a seronegative grey seal (halichoerus grypus) were exposed to a low doses of a cell culture-propagated phocine distemper virus isolate (pdv 2558/han 88). an intranasal route of inoculation was chosen. clinical signs, resembling those of 1988's seal disease and seroconversion were observed in both seronegative harbour seals. one of them succumbed to the infection. the virus was not transmitted to anot ...19902267888
phocine distemper in a harp seal (phoca groenlandica) from the gulf of st. lawrence, canada.the first case of phocine distemper in a seal from canadian waters and the first case of clinical phocine distemper in a harp seal, phoca groenlandica, is reported. a two-month-old female harp seal stranded on prince edward island in may 1991. significant clinical findings were lethargy and severe conjunctivitis. pulmonary congestion was the main necropsy finding, and histological lesions included diffuse demyelinating nonsuppurative encephalitis and mild multifocal interstitial pneumonia. acido ...19938445769
the use of monoclonal antibodies specific for seal immunoglobulins in an enzyme-linked immunosorbent assay to detect canine distemper virus-specific immunoglobulin in seal plasma samples.a method is described for the measurement of antigen-specific immunoglobulin in seal pup plasmas. four monoclonal antibodies (h1a, h13a, h24b and h49a) raised against grey seal (halichoerus grypus) immunoglobulin were used in an elisa procedure. levels of canine distemper virus (cdv) specific macroglobulin (igm like protein) were found to peak approximately 10 days after the first vaccination. levels of other smaller cdv-specific immunoglobulins (igg like protein) also increased after vaccinatio ...19938459104
prevalence of morbilliviruses among pinniped and cetacean species.since 1987, morbillivirus infections have caused serious disease outbreaks with high mortality among aquatic mammals. baikal seals (phoca sibirica) in siberia were involved in an outbreak caused by a virus closely related to canine distemper virus (cdv) in 1987. harbour seals (phoca vitulina) and grey seals (halichoerus grypus) in north-western europe were struck by a newly recognised morbillivirus of seals (pdv1). a serological survey has indicated that these morbillivirus infections frequently ...19938518442
morbillivirus infections of aquatic mammals: newly identified members of the genus.several disease outbreaks, which have caused the deaths of many thousands of seals and dolphins during the last decade, have now been attributed to infections with newly identified morbilliviruses. outbreaks in the late eighties amongst harbour seals (phoca vitulina) and grey seals (halichoerus grypus) in northwestern europe and amongst baikal seals (phoca sibirica) in siberia were caused by the newly discovered phocine distemper virus and by a strain of canine distemper virus, respectively. alt ...19958588316
morbillivirus infections in aquatic mammals.morbillivirus infections which were not documented in aquatic mammals until 1988, have caused at least five epizootics in these species during the last 10 years. affected populations include european harbour seals (phoca vitulina) and grey seals (halichoerus grypus) in 1998, baikal seals (phoca siberica) in siberia from 1987-1988, striped dolphins (stenella coeruleoalba) in the mediterranean sea from 1990-1992 and bottlenose dolphins (tursiops truncatus) along the eastern coast of the united sta ...19989807724
detection of canine distemper virus serum neutralizing antibodies in captive u.s. phocids.antibodies to morbilliviruses have been documented in free-ranging pinnipeds throughout populations in the atlantic and arctic oceans, but not from the pacific ocean. as a symbolic geographic barrier between the exposed atlantic and naive pacific populations, the captive phocid population in north america had undocumented serologic status. in this study, canine distemper virus (cdv) serum neutralization assays were used to assess the prevalence of antibodies in this population with participation ...201323505705
