title: Two types of Newcastle disease viruses isolated from feral birds in western Australia detected by monoclonal antibodies.
abstract: Thirteen viruses isolated from feral birds and one isolated from a domestic duck, obtained in 1979-1980 during a survey of birds in Western Australia, were shown to be Newcastle disease viruses of low virulence for chickens. The binding of mouse monoclonal antibodies, raised against NDV-Ulster 2C to MDBK cells infected with the isolates was assessed using an indirect immunoperoxidase test. Five viruses caused binding of all 9 monoclonal antibodies tested, whereas the other 9 isolates induced binding of only 4 monoclonal antibodies.
