A virus with rhabdovirus morphology which proved to be antigenically distinct from rabies virus and vesicular stomatitis virus was isolated from a dolphin that had beached on the Dutch coast. Neutralizing antibodies to this virus were found in several European marine mammal species.
Serological findings which had showed that the primary cause of the recent outbreak of serious disease of seals in the seas of North-Western Europe, is infection with canine distemper virus, were confirmed by in vivo and in vitro isolation of the virus from seals which had died at different locations during the outbreak. The virus which proved to be(More)
The cause of a recent outbreak of a serious disease of seals in the North and Baltic Seas, in which so far, over 9000 of the population of 16,000 animals have died, was investigated. Three viruses have been considered as the possible causative agents: a herpesvirus, a picornavirus and canine distemper virus. It was concluded mainly on the basis of(More)
An enzyme-linked immunosorbent assay (ELISA) for the detection and quantification of reovirus-specific IgM and IgG serum antibodies in rodents, detecting reovirus group reactive antibodies, was compared with reovirus types 1, 2 or 3 specific virus neutralization (VN) assays. To this end, serum samples were collected from specific pathogen-free (SPF) BALB/c(More)
The sensitivity of a newly developed enzyme-linked immunosorbent assay (ELISA) for detection of antibody to K virus was compared with the sensitivities of an immunofluorescence assay (IFA) and a hemagglutination inhibition assay (HIA). Specific pathogen-free BALB/c RIVM mice, 5 weeks old, were inoculated intraperitoneally with a mouse organ suspension(More)
An enzyme-linked immunosorbent assay (ELISA) was developed for the detection and quantification of IgM and IgG serum antibodies to mouse polyomavirus (MPV). To evaluate the potential of this ELISA for the screening of laboratory rodents, serum samples from specific pathogen free (SPF) BALB/c RIVM mice, collected after experimental intraperitoneal infection(More)
