| the fusion protein of peste des petits ruminants virus mediates biological fusion in the absence of hemagglutinin-neuraminidase protein. | to study the process of membrane fusion in morbilliviruses, the fusion (f) glycoproteins of peste des petits ruminants virus (pprv) and rinderpest virus (rpv) were expressed transiently in mammalian cells. the recombinant f proteins were found to be localized at the surface of transfected cells. the fusion activity, as evident from cell fusion assays and lysis of chicken erythrocytes, documented that transiently expressed pprv f glycoprotein induces cell fusion in the absence of homotypic hemagg ... | 2001 | 11601920 |
| the fusion protein of peste des petits ruminants virus is a hemolysin. | the fusion glycoprotein (f protein) of paramyxoviruses plays a vital role in virus-induced cytopathology. to explore the role of the f protein in peste des petits ruminants virus (pprv)-induced cytopathology, the f protein of pprv was purified by immunoaffinity chromatography. the purified f protein, when incubated with chicken erythrocytes, caused lysis suggesting that pprv f protein is a hemolysin. furthermore, the hemolysis can be inhibited by hyperimmune serum against f protein. the virus-in ... | 1999 | 10446657 |
| morbilliviruses and morbillivirus diseases of marine mammals. | in recent years, serious disease outbreaks among seals and dolphins were attributed to infection with established or newly recognized morbilliviruses. the first identification of a morbillivirus as causative agent of mass mortality among marine mammals was in 1988, when the previously unrecognized phocine distemper virus (pdv) caused the death of 20,000 harbor seals (phoca vitulina) in northwestern europe. a similar epizootic among baikal seals (phoca sibirica) in siberia in 1987 was later attri ... | 1995 | 8548190 |
| 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 ... | 1993 | 8518442 |
| neutralizing antibodies to phocine distemper virus in atlantic walruses (odobenus rosmarus rosmarus) from arctic canada. | the first evidence of phocine distemper virus (pdv) infection in atlantic walruses (odobenus rosmarus rosmarus) from nottingham island, northwest territories, canada, is reported. blood samples were collected from three male walruses killed by inuit hunters in the fall of 1990. differential virus neutralization test for each animal yielded higher titers against pdv than against other members of the morbillivirus genus including canine distemper, peste des petits ruminants, rinderpest and measles ... | 1994 | 8151831 |
| an outbreak of peste des petits ruminants in a zoological collection. | peste des petits ruminants virus was suspected to be the cause of a disease outbreak in a zoological collection at al ain in the arabian gulf. clinically the outbreak affected gazelles (gazellinae), ibex and sheep (caprinae) and gemsbok (hippotraginae); subclinical involvement of nilgai (tragelaphinae) was suspected. a morbillivirus was isolated and using monoclonal antibodies and biological tests in cattle, sheep and goats the virus of peste des petits ruminants was identified. | 1987 | 3424615 |
| characterisation of the european seal morbillivirus. | the elisa test originally developed for the detection of serum antibodies to rinderpest virus has been shown to detect cross-reacting antibodies in sera of diseased common and grey seals. analysis of sera collected from various seal populations is in progress to establish the correlation between different morbillivirus neutralisation tests, elisa tests and the disease status of the animals. rna purified from post-mortem tissues removed from diseased seals has been analysed by hybridisation with ... | 1990 | 2402877 |
| round table on morbilliviruses in marine mammals. | since 1988 morbilliviruses have been increasingly recognized and held responsible for mass mortality amongst harbour seals (phoca vitulina) and other seal species. virus isolations and characterization proved that morbilliviruses from seals in northwest europe were genetically distinct from other known members of this group including canine distemper virus (cdv), rinderpest virus, peste des petits ruminants virus and measles virus. an epidemic in baikal seals in 1987 was apparently caused by a m ... | 1992 | 1481361 |
