| 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) |
|---|
| bovine respiratory syncytial virus | A pneumovirus causing an emerging disease in young cattle characterised by pneumonia, interstitial pulmonary oedema, and emphysema; sheep are also susceptible to the virus. (05 Mar 2000) |

| virus, respiratory syncytial | A virus that causes mild respiratory infections (colds and coughs) in adults but in young children can produce severe respiratory problems (bronchitis and pneumonia). Effective immunity against rsv requires a continuous solid level of antibodies against the virus. There is particular concern for rsv in premature babies because of their lack of maturity and lack of antibodies. (12 Dec 1998) |
| 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 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) |
| respiratory syncytial viruses | A group of viruses in the pneumovirus genus causing respiratory infections in various mammals. Humans and cattle are most affected but infections in goats and sheep have also been reported. (12 Dec 1998) |
| syncytial | Relating to a syncytium. (05 Mar 2000) |
| syncytial bud | A localised aggregation of syncytiotrophoblastic nuclei in the villi of the placenta during early pregnancy. Synonym: syncytial bud, syncytial sprout. (05 Mar 2000) |
| syncytial knot | A localised aggregation of syncytiotrophoblastic nuclei in the villi of the placenta during early pregnancy. Synonym: syncytial bud, syncytial sprout. (05 Mar 2000) |
| syncytial sprout | A localised aggregation of syncytiotrophoblastic nuclei in the villi of the placenta during early pregnancy. Synonym: syncytial bud, syncytial sprout. (05 Mar 2000) |
| syncytial trophoblast | The syncytial outer layer of the trophoblast; site of synthesis of human chorionic gonadotropin. See: trophoblast. Synonym: placental plasmodium, plasmodial trophoblast, plasmodiotrophoblast, syncytial trophoblast, syntrophoblast. Origin: syncytium + trophoblast (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) |
| swine infertility and respiratory syndrome virus | A species of arterivirus causing reproductive and respiratory disease in pigs. The european strain is called lelystad virus. Airborne transmission is common. (12 Dec 1998) |
| papilloma virus, human | A family of over 60 viruses responsible forcausing warts. The majority of the viruses produce warts on the hands, fingers, and even the face. most of these viruses are innocuous, causing nothing more than cosmetic concerns. Several types of HPV are confined primarily to the moist skin of the genitals, producing genital warts and elevating the risk for cancer of the cervix. These viruses that cause wartlike growths on the genitals and contrribute to cancer of the cervix are sexually transmitted. (12 Dec 1998) |
| 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) |
