Gammaretrovirus
| Definition: |
A genus of RETROVIRIDAE comprising endogenous sequences in mammals, related RETICULOENDOTHELIOSIS VIRUSES, AVIAN, and a reptilian virus. Many species contain oncogenes and cause leukemias and sarcomas. |
| Notes: |
infection: coord IM with RETROVIRIDAE INFECTIONS (IM) + TUMOR VIRUS INFECTIONS (IM) |
| Also Called: |
Tumor Viruses, Murine,Viper retrovirus |
Gammaretrovirus Categories.
 |
Leukemia Virus, Feline - A species of GAMMARETROVIRUS causing leukemia, lymphosarcoma, immune deficiency, or other degenerative diseases in cats. Several cellular oncogenes confer on FeLV the ability to induce sarcomas (see also SARCOMA VIRUSES, FELINE). |
|
Leukemia Virus, Gibbon Ape - A species of GAMMARETROVIRUS causing leukemia in the gibbon ape. Natural transmission is by contact. |
|
Leukemia Virus, Murine - Species of GAMMARETROVIRUS, containing many well-defined strains, producing leukemia in mice. Disease is commonly induced by injecting filtrates of propagable tumors into newborn mice. |
|
Reticuloendotheliosis Viruses, Avian - A group of viruses in the genus GAMMARETROVIRUS comprising a few isolates from birds, with no known corresponding endogenous relatives. |
|
Sarcoma Virus, Woolly Monkey - A species of GAMMARETROVIRUS producing tumors in primates. Originally isolated from a fibrosarcoma in a woolly monkey, WMSV is a replication-defective v-onc virus which carries the sis oncogene. In order to propagate, WMSV requires a replication-competent helper virus. |
|
Sarcoma Viruses, Feline - Species of GAMMARETROVIRUS isolated from fibrosarcoma in cats. The viruses are actually recombinant feline leukemia viruses (FeLV) where part of the genome has been replaced by cellular oncogenes. It is unique to individuals and not transmitted naturally to other cats. FeSVs are replication defective and require FeLV to reproduce. |
