A virus, first isolated in Japan, that causes an important and widespread infection of laboratory mice; it belongs to the Paramyxoviridae. The virus is widely used in cell fusion studies. The viruses so modify the surfaces of infected cells that they tend to fuse. Even UV-killed viruses adsorb on host cells and promote their fusion. See Chronology, 1965, Harris and Watkins; enveloped viruses.
