| virus-transformed cell | A cell that has been genetically changed to a tumour cell, the change being subsequently tramsmitted to all descendent cell's; cell's transformed by oncornaviruses continue to produce virus in high concentration without being killed; DNA tumour virus-transformed cell's develop (along with other changes) tumour-associated antigens and rarely produce virus.

| Patois virus | A serologic group of the genus Bunyavirus, comprising 4 species. (05 Mar 2000) |
| Visna maedi virus | <virology> A retrovirus of sheep and goats. A member of the lentivirus subfamily related to HIV. First identified in Iceland when it was introduced by sheep imported from Germany and causes two diseases the most common, maedi, is a pulmonary infection (maedi is Icelandic for shortness of breath) and when it infects the nervous system, visna, a paralysis similar to multiple sclerosis (visna is Icelandic for wasting). (18 Nov 1997) |
| visna-maedi virus | A species of lentivirus, subgenus ovine-caprine lentiviruses (lentiviruses, ovine-caprine), that can cause chronic pneumonia (maedi), mastitis, arthritis, and encephalomyelitis (visna) in sheep. Maedi is a progressive pneumonia of sheep which is similar to but not the same as jaagsiekte (pulmonary adenomatosis, ovine). Visna is a demyelinating leukoencephalomyelitis of sheep which is similar to but not the same as scrapie. (12 Dec 1998) |
| visna virus | <virology> A virus in the subfamily Lentivirinae which causes encephalitis andchronic pneumonitis in sheep. (09 Oct 1997) |
| REO virus | <virology> A genus of viruses (family Reoviridae) that are 75 to 80 nm in diameter, with distinct double layers of capsomeres, and have vertebrates as hosts; a causative relationship to illness has not been proven. They have been recovered from children with mild fever and sometimes diarrhoea, and from children with no apparent infection; from chimpanzees with coryza; monkeys and mice; and cattle faeces. There are three antigenically distinct human types related by a common complement-fixing antigen.

| CELO virus | <virology> A virus with characteristics of adenovirus, and similar to quail bronchitis virus. Synonym: chicken embryo lethal orphan virus. (05 Mar 2000) |
| medi virus | A retrovirus (subfamily Lentivirinae) that is the cause of maedi; it is very similar to the visna virus Synonym: medi virus, progressive pneumonia virus. (05 Mar 2000) |
| Central European tick-borne encephalitis virus | One of the virus's of the tick-borne encephalitis complex of group B arboviruses (genus Flavivirus); the causative agent of tick-borne encephalitis (Central European subtype). (05 Mar 2000) |
| respiratory enteric orphan virus | A nonenveloped icosahedral virus whose genome consists of double stranded RNA, belonging to the family Reoviridae, frequently found in both the respiratory and enteric tract. Synonym: REO virus. (05 Mar 2000) |
| respiratory syncytial virus | <virology> This RNA virus is a member of the Paramyxoviridae family and is a major pathogen in the upper and lower respiratory tract in both infants and younger children. Respiratory syncytial virus manifestations include bronchiolitis, pneumonia and croup. Acronym: RSV (27 Sep 1997) |
| respiratory syncytial virus, bovine | A species of pneumovirus causing an important respiratory infection in cattle. Symptoms include fever, conjunctivitis, and respiratory distress. (12 Dec 1998) |
| respiratory syncytial virus, human | The type species of pneumovirus and an important cause of lower respiratory disease in infants and young children. It frequently presents with bronchitis and bronchopneumonia and is further characterised by fever, cough, dyspnea, wheezing, and pallor. (12 Dec 1998) |
| respiratory syncytial virus infections | Pneumovirus infections caused by the respiratory syncytial viruses. Humans and cattle are most affected but infections in goats and sheep have been reported. (12 Dec 1998) |
| VS virus | <virology> Rhabdovirus causing the disease soremouth in cattle. Widely used as a laboratory tool especially in studies on the spike glycoprotein as a model for the synthesis, post translational modification and export of membrane proteins. (18 Nov 1997) |
