| mammary tumour virus | <organism, virology> Retrovirus that induces mammary carcinoma in mice. Isolated from highly inbred strains that had very high incidence of the tumours, after the discovery that the disease was transmitted by nursing mothers in milk. Endogenous provirus present in germ line of all inbred mice. Transcription of the provirus is regulated by a viral promoter that increases transcription in response to glucocorticoid hormones. May transform by proviral insertion activating the cellular int 1 oncogene (18 Nov 1997) |

| mammary tumour virus of mice | Member of the retrovirus subfamily Oncornavirinae, antigenically distinct from the murine leukaemia-sarcoma complex, that is associated with adenocarcinomatous tumours of the mammary gland, commonly latent in wild and laboratory mice and causing cancer only in genetically susceptible strains under certain hormonal influences. Synonym: Bittner agent, Bittner virus, Bittner's milk factor, mammary cancer virus of mice, milk factor, mouse mammary tumour virus. (05 Mar 2000) |
| papular stomatitis virus of cattle | A poxvirus of the genus Parapoxvirus, reported from North America, Africa and Europe, causing bovine papular stomatitis. Synonym: papular stomatitis virus of cattle. (05 Mar 2000) |
| rat sialodacryoadenitis virus | A coronavirus causing sialodacryoadenitis in rats. (05 Mar 2000) |

| parainfluenza virus | <virology> Species of the Paramyxoviridae, there are four types. Type 1 is also called Sendai virus or Haemagglutinating virus of Japan (HVJ) and the inactivated form is used to bring about cell fusion. Types 2-4 cause mild respiratory infections in humans. (18 Nov 1997) |
| Rauscher's virus | An RNA retrovirus associated with leukaemia in rodents; similar to Friend virus. Synonym: Rauscher's virus. (05 Mar 2000) |
| parainfluenza virus 1, human | The type species of paramyxovirus also called haemadsorption virus 2 (ha2), which causes laryngotracheitis in humans, especially children. (12 Dec 1998) |

| parainfluenza virus 2, human | A species of rubulavirus associated particularly with acute laryngotracheitis (croup) in children aged 6 months to 3 years. (12 Dec 1998) |
| parainfluenza virus 3, human | A species of paramyxovirus frequently isolated from small children with pharyngitis, bronchitis, and pneumonia. (12 Dec 1998) |
| Venezuelan equine encephalomyelitis virus | A group A arbovirus of the genus Alphavirus, family Togaviridae, occurring in Venezuela and several other South American countries, in Panama and Trinidad, and occasionally the United States causing Venezuelan equine encephalomyelitis in horses and humans; it seems to be more viscerotropic than neurotropic; the virus is transmitted by Culex mosquitoes. Synonym: VEE virus. (05 Mar 2000) |
