Avian Metaavulavirus 2
''Avian metaavulavirus 2'', formerly ''Avian paramyxovirus 2'', is a species of virus belonging to the family ''Paramyxoviridae'' and genus ''Metaavulavirus''. The virus is a negative strand RNA virus containing a monopartite genome. ''Avian metaavulavirus 2'' is one of nine species belonging to the genus ''Metaavulavirus''. The most common serotype of ''Avulavirinae'' is serotype 1, the cause of Newcastle disease (ND). ''Avian metaavulavirus 2'' has been known to cause disease, specifically mild respiratory infections in domestic poultry, including domestic turkey, turkeys and chickens, and has many economic effects on egg production and Poultry farming, poultry industries. The virus was first isolated from a strain in Yucaipa, California in 1956. Since then, other isolates of the virus have been isolated worldwide. Viral classification ''Avian metaavulavirus 2'' is a negative sense RNA virus with a monopartite genome. It belongs to Baltimore classification#Group V: Single- ...

Paramyxoviridae
''Paramyxoviridae'' (from Ancient Greek, Greek ''para-'' “by the side of” and ''myxa'' “mucus”) is a family of negative-strand RNA viruses in the order ''Mononegavirales''. Vertebrates serve as natural hosts. Diseases associated with this family include measles, mumps, and respiratory tract infections. The family has four subfamilies, 17 genera, and 78 species, three genera of which are unassigned to a subfamily. Structure Virions are enveloped and can be spherical or pleomorphic and capable of producing filamentous virions. The diameter is around 150 nm. Genomes are linear, around 15kb in length. Fusion proteins and attachment proteins appear as spikes on the virion surface. Matrix proteins inside the envelope stabilise virus structure. The nucleocapsid core is composed of the genomic RNA, nucleocapsid proteins, phosphoproteins and polymerase proteins. Genome The genome is nonsegmented, negative-sense RNA, 15–19 kilobases in length, and contains six to 10 gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
