Avian Paramyxovirus (APMV)

Avian Paramyxovirus (APMV) Antibody Products by Targets


Avian paramyxoviruses (APMVs) have emerged as a major threat to the global poultry industry. Avulaviruses (formerly Rubulaviruses) are members of the genus Avulavirus (formerly Rubulaviruses), the family Paramyxoviridae, and the order Mononegavirales. They have been isolated from over 200 different wild and domestic bird species all over the world. In a variety of avian hosts, 22 different APMV species have been identified. Orthoavulavirus (APMV-1, -9, -12, -13, -16 to -19, and -21), Metaavulavirus (APMV-2, -5 to -8, -10, -11, -14, -15, -20, and -22), and Paraavulavirus are the three genera (APMV-3 and -4). APMV serotypes are found all over the world. The most important pathogen of this group for poultry is Newcastle disease virus (APMV-1); however, APMV-2, -3, -6, and -7 are occasionally associated with disease in chickens and turkeys.

Viral Genome and Proteins

APMVs are single-stranded, negative-sense RNA viruses with a lipid envelope that measure about 150 nm in diameter. The viral genomes range in size from 13 to 19 kb and encode six non-overlapping genes in the sequence 3'-N-P/V-M-F-HN-L-5'. Their viral RNA encodes six major proteins: nucleocapsid protein (NP), phosphoprotein (P), matrix protein (M), fusion protein (F), haemagglutinin-neuraminidase (HN), large RNA polymerase (L), and two non-structural proteins V and W. APMV-6 differs from other APMVs in that it has a small hydrophobic protein (SH) gene between the F and HN genes.
