| 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) |
| 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) |
| Murray Valley encephalitis virus | A group B arbovirus of the genus Flavivirus that causes Murray Valley encephalitis; it is transmitted by Culex mosquitoes, and also infects birds and horses. Synonym: Australian X disease virus, MVE virus. (05 Mar 2000) |
| Murutucu virus | A C group mosquito-borne virus of the genus Bunyavirus, which has caused undifferentiated type fever in Brazil and French Guiana. (05 Mar 2000) |
| plum pox virus | A species of the genus potyvirus that affects many species of prunus. It is transmitted by aphids and by infected rootstocks. (12 Dec 1998) |
| contagious ecthyma virus of sheep | The poxvirus of the genus Parapoxvirus causing contagious ecthyma (pustular dermatitis) of sheep. Synonym: soremouth virus, pustular dermatitis virus (05 Mar 2000) |
| contagious pustular stomatitis virus | The poxvirus causing horsepox. Synonym: contagious pustular stomatitis virus. (05 Mar 2000) |
| pneumonia virus of mice | An RNA virus of the genus Pneumovirus, a member of the family Paramyxoviridae, occurring normally as latent infection in laboratory mice, but capable of activation by serial intranasal passage and causing pneumonia. Synonym: PVM virus. (05 Mar 2000) |
| poliomyelitis virus | The picornavirus (genus Enterovirus) causing poliomyelitis in humans; the route of infection is the alimentary tract, but the virus may enter the bloodstream and nervous system, sometimes causing paralysis of the limbs and, rarely, encephalitis; many infections are inapparent; serologic types 1, 2, and 3 are recognised, type 1 being responsible for most paralytic poliomyelitis and most epidemics. Synonym: poliovirus hominis, poliovirus. (05 Mar 2000) |
| MVE virus | A group B arbovirus of the genus Flavivirus that causes Murray Valley encephalitis; it is transmitted by Culex mosquitoes, and also infects birds and horses. Synonym: Australian X disease virus, MVE virus. (05 Mar 2000) |
| myeloblastosis virus, avian | A species of avian type c retroviruses (retroviruses type c, avian) causing anaemia in fowl. (12 Dec 1998) |
| cowpox virus | A species of orthopoxvirus that is the aetiologic agent of cowpox. It is closely related to but antigenically different from vaccina virus. (12 Dec 1998) |
| Coxsackie virus | <virology> A group of picornaviruses, included in the genus Enterovirus, first isolated in a village called Coxsackie, New York, USA. Coxsackie virus has a spherical shape, about 28 nm in diameter, and causes myositis, paralysis, and death in young mice, and is responsible for a variety of diseases in man, and probably accounts for as many as 50% of all cases of viral pericarditis and myocarditis. Other infections include; herpangina, aseptic meningitis, a common-cold-like syndrome, a non-paralytic poliomyelitis-like syndrome, epidemic pleurodynia, and a serious myocarditis. Also causes hand, foot and mouth disease. They are divided antigenically into two groups, A and B, each of which includes a number of serological types. Coxsackie A viruses are divided into 24 serotypes and are associated with or implicated in herpangina, hand-foot-and-mouth disease, aseptic meningitis, paralytic disease, encephalitis, ataxia, acute onset juvenile diabetes, and cardiac diseases with diffuse myositis. Coxsackie A24 variant can cause acute haemorrhagic conjunctivitis. Coxsackie B is divided into 6 serotypes and associated with epidemic pleurodynia (b1, b3), myocarditis and endocarditis (b3, b1), respiratory disorders (b3, b5), and kidney, pancreas, and liver disorders. It can also produce focal areas of degeneration in brain and skeletal muscle. Similar to polioviruses in chemical and physical properties. Origin: Coxsackie, N.Y., where first isolated (08 Mar 2000) |
