| retrovirus | <virology> Any virus in the family Retroviridae that has RNA as its nucleic acid and uses the enzyme reverse transcriptase to copy its genome into the DNA of the host cells chromosomes. Many cancers in vertebrates are caused by retroviruses. (09 Oct 1997) |
|---|---|
| endogenous retrovirus | <virology> A retrovirus that has become dormant and exists as DNA copies in every cell in the body of its host and is passed down from generation to generation. (09 Oct 1997) |
| avian | <zoology> Relating to, affecting, resembling or derived from a bird. (02 Jan 1998) |
| avian achondroplasia | <veterinary> An achondroplasia seen in several breeds of domestic chickens. Inheritance: autosomal dominant. (05 Mar 2000) |
| avian adenovirus type 1 proteinase | <enzyme> 206 aa residues of which 66% are homologous to human ad2 emzyme embl/genbank l13161 Registry number: EC 3.4.22.- Synonym: aavl proteinase, aavl endopeptidase (26 Jun 1999) |
| avian diphtheria | An infection by the fowlpox virus in which tracheal involvement is especially severe. See: fowlpox. Synonym: fowl diphtheria. (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 | <veterinary> An expression of disease of the avian leukosis-sarcoma complex; characterised by severe anaemia and large numbers of erythroblasts in the blood; chickens are most susceptible but fatal natural infections have been reported in guinea fowl. Synonym: fowl erythroblastosis. (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 herpesvirus 1 | <virology> A virus causing avian infectious laryngotracheitis in chickens. (05 Mar 2000) |
| avian herpesvirus 2 | <virology> A virus causing Marek's disease in chickens. (05 Mar 2000) |
| avian infectious encephalomyelitis | <veterinary> A disease of very young chicks caused by a picornavirus and characterised by tremor, ataxia, somnolence, and finally death. Synonym: epidemic tremor. (05 Mar 2000) |
| avian infectious laryngotracheitis virus | <virology> A herpesvirus causing avian infectious laryngotracheitis. (05 Mar 2000) |
| avian influenza | Infection of domestic and wild fowl and other birds with influenza a virus, avian. (12 Dec 1998) |
| avian influenza virus | <virology> A type A influenza virus (genus Influenzavirus) that causes fowl plague. Synonym: fowl plague virus. (05 Mar 2000) |
