| tumour viruses, murine | Species of mammalian type c retroviruses (retroviruses type c, mammalian) that cause solid tumours or leukaemias in mice. (12 Dec 1998) |
|---|---|
| Koongol viruses | A serologic group of the genus Bunyavirus, comprising two species, Koongol (type species) and Wongal virus. (05 Mar 2000) |
| fibrous bacterial viruses | Deoxyribonucleoproteins that "infect" and replicate in Gram-negative bacteria having sex pili and that, unlike bacteriophage, are released from infected bacteria without damage to the cell; they seem to be of two kinds, one of which has a specificity for F pili and the other for I pili. Synonym: fibrous bacterial viruses. (05 Mar 2000) |
| filamentous bacterial viruses | Deoxyribonucleoproteins that "infect" and replicate in Gram-negative bacteria having sex pili and that, unlike bacteriophage, are released from infected bacteria without damage to the cell; they seem to be of two kinds, one of which has a specificity for F pili and the other for I pili. Synonym: fibrous bacterial viruses. (05 Mar 2000) |
| uukuniemi group viruses | A group of viruses in the genus phlebovirus of the family bunyaviridae, infecting vertebrates and vectored by ticks. Its members have not been associated with human disease though antibodies have been isolated from human sera. (12 Dec 1998) |
| foamy viruses | Retroviruses of the subfamily Spumavirinae, found in primates and other mammals; so named because of lacelike changes produced in monkey kidney cells; syncytia are also produced. Synonym: foamy agents. (05 Mar 2000) |
| lcm-lassa complex viruses | One of two groups of viruses in the arenavirus genus and considered part of the old world complex. It includes lassa virus and lymphocytic choriomeningitis virus, although the latter has worldwide distribution now. (12 Dec 1998) |
| leukaemia viruses, murine | Species of mammalian type c retroviruses (retroviruses type c, mammalian) producing leukaemia in mice. It is commonly induced by injecting filtrates of propagable tumours into newborn mice. The gross strain (gross virus) occurs spontaneously in inbred mice, but none of the other strains occurs naturally. (12 Dec 1998) |
