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

| avian leukosis | A group of transmissible, virus-induced diseases of chickens, characterised by proliferation of immature erythroid, myeloid, or lymphoid cells. It includes both leukaemic and solid-tumour forms. (12 Dec 1998) |

| avian monocytosis | An acute or subacute disease of young laying chickens characterised by lowered egg production, diarrhoea, frequently cyanosis of the head, and pathologic changes involving chiefly the liver and kidney; aetiology is not definitely established. Synonym: avian monocytosis. (05 Mar 2000) |
| avian myeloblastosis | Disease caused by the avian leukosis-sarcoma virus, which belongs to the family Retroviridae, characterised by progressive anaemia, enormous numbers of myeloblasts in the blood, weakness, and death. (05 Mar 2000) |

| avian neurolymphomatosis virus | The herpesvirus that causes avian lymphomatosis (Marek's disease); is distinct from those causing other forms of leukosis. Synonym: avian lymphomatosis virus, fowl neurolymphomatosis virus, Marek's disease virus. (05 Mar 2000) |

| avian trichomoniasis | Trichomoniasis occurring in the upper digestive tract in a variety of birds and caused by Trichomonas gallinae; it causes necrotic ulceration in the mouth, oesophagus, crop, and proventriculus, frequently with rapid weight loss and death. (05 Mar 2000) |
| avian viral arthritis virus | A virus of the genus Reovirus, family Reoviridae, causing tenosynovitis and arthritis in chickens. (05 Mar 2000) |
