Newcastle Disease Virus (Paramyxoviridae)

2021
Newcastle disease (ND) is one of the most important infectious diseases of poultry. It is caused by virulent Avian avulavirus 1 (AAvV-1), also known as Newcastle disease virus (NDV) or Avian paramyxovirus 1 (APMV-1). Since the mid-1920s, ND has spread throughout the world.

Newcastle Disease Virus

2014
Newcastle disease virus (NDV), a member of the Avulavirus genus in the Paramyxoviridae family, has a ribonucleic acid (RNA) genome that is negative sense, nonsegmented and single-stranded. The genome codes for six structural proteins: nucleocapsid, phosphoprotein (P), matrix, fusion, hemagglutinin–neuraminidase and the RNA-directed RNA polymerase, in ...

Hæmolysis by Newcastle Disease Virus

Nature, 1949
FOR a number of years it has been known in this laboratory that haemolysis of moderate degree may occur when red cells are being treated with the viruses of mumps and Newcastle disease. This is not characteristic of any of the influenza viruses. The haemolysis was of slight degree and apparently irregular in its occurrence.

Precipitation reactions with Newcastle disease virus

Tropical Animal Health and Production, 1995
Acid precipitated and detergent treated Newcastle disease virus (NDV) antigen was prepared and characterised using the agar gel precipitation (AGP) test. The detergent treated NDV antigen was used to screen antibodies to NDV and the results compared with the conventional haemagglutination inhibition (HI) test titres.

Newcastle Disease Virus Variations

1990
Variation among Newcastle disease variations (NDV) strains has traditionally been by functional tests, e.g., virulence, thermostability of the hemagglutinin, plaguing ability. Variation has recently been described at the genetic level by gene cloning and at the antigenic level by monoclonal antibodies (MAb); in this chapter we discuss these two factors

Chemical mutagenesis of Newcastle disease virus

Virology, 1963
Abstract In vitro treatment of wild-type Newcastle disease virus with nitrous acid produced three distinct mutations: the “red”-plaque, the small-plaque, and the minute-plaque types. The mutation from white to red character was independent of the plaque-size mutations.

Newcastle disease virus: An evolving pathogen?

Avian Pathology, 2001
Australia experienced outbreaks of virulent Newcastle disease (ND) in chickens in the state of New South Wales in the years 1998, 1999 and 2000. The disease had occurred previously in Australia in 1930 and 1932 but the country was free of it until the recent outbreaks. Avirulent strains of Newcastle disease virus (NDV) were detected in 1966 and, during

Newcastle Disease Virus Replication

1988
Newcastle disease virus (NDV) has long been known as one of the most diverse and deadly avian pathogens. The replication cycle of NDV has also been studied effectively as a prototype for the Paramyxoviridae family of negative strand RNA viruses (1). In this role, NDV has several distinct advantages. It is easy to work with in cell culture because it is

Newcastle Disease Virus Antigens and Strain Variations

American Journal of Veterinary Research, 1975
SUMMARY Study of antigenic differences among strains of Newcastle disease virus is complicated by the presence in most field isolates and strains of several genetically distinct plaque populations, and by differences in avidity (reactions to antibody) among Newcastle disease viruses.
