(SeV), also known as murine parainfluenza virus type 1 or hemagglutinating virus of Japan (HVJ), is a negative sense, single-stranded RNA virus
of the Paramyxoviridae
family, a group of viruses featuring, notably, the Morbillivirus
genera. SeV is a member of the paramyxovirus subfamily Paramyxovirinae
, genus Respirovirus
, members of which primarily infect mammals.
SeV is responsible for a highly transmissible respiratory tract infection in mice, hamsters, guinea pigs, rats, and occasionally pigs, with infection passing through both air and direct contact routes. The virus can be detected in mouse colonies worldwide, generally in suckling to young adult mice. Epizootic
infections of mice are usually associated with a high mortality rate, while enzootic
disease patterns suggest that the virus is latent and can be cleared over the course of a year.
A novel and well-recognized use for SeV is the fusion of eukaryotic cells, especially to produce hybridoma
cells capable of manufacturing monoclonal antibodies
in large quantities.
Diagnosis and Prophylaxis
SeV induces lesions within the respiratory tract, usually associated with bacterial inflammation of the trachea and lung (tracheitis
, respectively). However, the lesions are... Read More
