| reticuloendotheliosis virus, avian | A species of reticuloendotheliosis viruses of the genus retroviruses type b, mammalian that causes a chronic neoplastic and a more acute immunosuppressive disease in fowl. (12 Dec 1998) |
|---|---|
| myeloblastosis virus, avian | A species of avian type c retroviruses (retroviruses type c, avian) causing anaemia in fowl. (12 Dec 1998) |
| infectious bronchitis virus, avian | A species of coronavirus causing infections in chickens and possibly pheasants. Chicks up to 4 weeks old are the most severely affected. (12 Dec 1998) |
| influenza a virus, avian | Strains of influenza a virus causing influenza in birds. Transmission is caused by close contact or is waterborne in aquatic species. (12 Dec 1998) |
| encephalomyelitis virus, avian | A species of enterovirus infecting primarily young chicks, but also found in turkeys, pheasants, and guinea fowl. It causes a fatal neuronal degeneration and is transmitted by mechanical contact. (12 Dec 1998) |
| erythroblastosis virus, avian | A species of avian type c retroviruses (retroviruses type c, avian) causing progressive anaemia and weakness in domestic and wild fowl. (12 Dec 1998) |
| leukosis virus, avian | The type species of avian type c retroviruses (retroviruses type c, avian) producing latent or manifest lymphoid leukosis in fowl. (12 Dec 1998) |
| Rous sarcoma virus | <virology> The virus responsible for the classic first cell free transmission of a solid tumour, the chicken sarcoma, first reported by Rous in 1911. An avian C type oncorna virus, original source of the src oncogene. (18 Nov 1997) |
| Rous sarcoma virus protease | <enzyme> Has been sequenced; crystallographic structure has been determined Registry number: EC 3.4.23.- Synonym: protease, rous sarcoma virus, rous sarcoma virus aspartic protease (26 Jun 1999) |
| Moloney murine sarcoma virus | <molecular biology, virology> Replication defective retrovirus, source of the oncogene v mos, responsible for inducing fibrosarcomas in vivo and transforming cells in culture. (18 Nov 1997) |
| moloney sarcoma virus | A replication-defective murine sarcoma virus (sarcoma viruses, murine) isolated from a rhabdomyosarcoma by moloney in 1966. (12 Dec 1998) |
| murine sarcoma virus | A seemingly defective retrovirus that produces sarcomas in mice when growing in the presence of a "helper" virus; e.g., mouse leukaemia virus. (05 Mar 2000) |
| porcine sarcoma virus | A retrovirus causing sarcoma in swine. (05 Mar 2000) |
| Harvey sarcoma virus | <oncogene> One of a family of oncogenes, first identified as transforming genes of Harvey and Kirsten murine sarcoma viruses. (Name from rat sarcoma because Harvey virus, though a mouse virus, obtained its transforming gene during passage in a rat). Transforming protein coded is p21ras, a GTP-binding protein with GTPase activity, that resembles regulatory G-proteins. (18 Nov 1997) |
| sarcoma virus | <virology> Virus that causes tumours originating from cells of connective tissue such as fibroblasts. See: Rous sarcoma virus, src. (18 Nov 1997) |
