Newcastle disease virus

Newcastle disease virus (NDV) is one of the most important of the nine serogroups of avian paramyxoviruses. It is also referred to as Avian paramyxovirus type 1 (APMV-1). NDV is a negative-sense, single-stranded RNA virus. There are several different strains of NDV, which range in severity depending on the strain.

Virulent Newcastle Disease (VND) is an acute, highly contagious systemic disease of most species of birds, caused by virulent strains of avian paramyxovirus type 1 (APMV-1). Chickens, turkeys, quail and other gallinaceous birds are highly susceptible, but ducks and geese are relatively resistant.

NDV is destroyed by exposure to heat, irradiation (ultraviolet rays and sunlight), pH, oxidation and several chemical compounds. However the rate of its destruction varies depending on the NDV strain. The virus can remain infectious in the environment for several days to weeks.
