| immunodeficiency virus, bovine | A species of lentivirus, subgenus bovine lentiviruses (lentiviruses, bovine), found in cattle and causing lymphadenopathy, lymphocytosis, central nervous system lesions, progressive weakness, and emaciation. It has immunological cross-reactivity with other lentiviruses including HIV. (12 Dec 1998) |

| infectious bovine rhinotracheitis virus | A herpesvirus causing infectious bovine rhinotracheitis. Synonym: IBR virus. (05 Mar 2000) |
| enteric cytopathogenic bovine orphan virus | Former name for early isolates of bovine enteroviruses. Synonym: enteric cytopathogenic bovine orphan virus. (05 Mar 2000) |
| ephemeral fever virus, bovine | The type species of ephemerovirus causing disease in cattle. Transmission is by haematophagous arthropods and the virus has been isolated from both culicoides and mosquitoes. (12 Dec 1998) |
| abelson leukaemia virus | A defective murine leukaemia virus capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukaemia after superinfection with friend, moloney, or rauscher virus. (12 Dec 1998) |
| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (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. (02 Jan 1998) |
| radiation leukaemia virus | A murine leukaemia virus isolated from radiation-induced lymphomas in c57bl mice. It is leukemogenic, thymotrophic, can be transmitted vertically, and replicates only in vivo. (12 Dec 1998) |
| Maloney leukaemia virus | A retrovirus associated with leukaemia in rodents. (05 Mar 2000) |
| Rauscher leukaemia virus | An RNA retrovirus associated with leukaemia in rodents; similar to Friend virus. Synonym: Rauscher's virus. (05 Mar 2000) |
| Gross' leukaemia virus | A strain of mouse leukaemia virus. Synonym: Gross' leukaemia virus. (05 Mar 2000) |
| moloney leukaemia virus | A murine virus arising during the propagation of s37 mouse sarcoma, and causing lymphoid leukaemia in mice. It also infects rats and newborn hamsters and is apparently transmitted vertically to embryos in utero and through mother's milk. (12 Dec 1998) |
| Moloney murine leukaemia virus | <molecular biology, virology> Replication competent retrovirus (Oncovirinae) that causes leukaemia in mice, isolated by Moloney from cell free extracts made from a transplantable mouse sarcoma. (18 Nov 1997) |
| murine leukaemia virus | <virology> A group of type C retroviruses infecting mice and causing in some strains lymphatic leukaemia after a long latent period. Nearly all are replication competemt and v onc minus. See: Abelson leukaemia virus. (18 Nov 1997) |
| human T-cell leukaemia virus | <virology> One of a group of retroviruses which causes the disease T-cell leukaemia in humans. T-cell leukaemia is a type of the cancer leukaemia where the body uncontrollably produces large amounts of abnormal (nonworking) T lymphocytes. (09 Oct 1997) |
