| Aujeszky's disease virus | A herpesvirus causing pseudorabies in swine. Synonym: Aujeszky's disease virus. (05 Mar 2000) |
| Australian X disease virus | A group B arbovirus of the genus Flavivirus that causes Murray Valley encephalitis; it is transmitted by Culex mosquitoes, and also infects birds and horses. Synonym: Australian X disease virus, MVE virus. (05 Mar 2000) |
| avian encephalomyelitis virus | <virology> A virus of the genus Enterovirus (family Picornaviridae) causing avian infectious encephalomyelitis in young chicks. (05 Mar 2000) |
| avian erythroblastosis virus | <virology> Group of C type RNA tumour viruses (Oncovirinae) that cause various leukaemias and other tumours in birds. The acute leukaemia viruses, that are replication defective and require helper viruses, include avian erythroblastosis (AEV), myeloblastosis (AMV) and myelo cytomatosis viruses. AEV carries two transforming genes, v erbA and v erbB, the cellular homologue of the latter is the structural gene for the epidermal growth factor receptor. AMV carries v myb and causes a myeloid leukaemia, avian myelocytomatosis virus carries v myc. The avian lymphatic leukaemia viruses (ALV) are also Retroviridae but are replication competent and induce neoplasia only after several months, they often occur in conjunction with replication defective leukaemia viruses. (02 Jan 1998) |

| avian influenza virus | <virology> A type A influenza virus (genus Influenzavirus) that causes fowl plague. Synonym: fowl plague virus. (05 Mar 2000) |
