| a hitherto unreported paramyxovirus of turkeys. | a newly isolated avian virus is described which was obtained from a flock of laying turkey hens with respiratory disease and accompanying egg production drop. characterisation of the virus indicated it to be of the paramyxovirus group and to be related through antigenic crossing with newcastle disease virus. examination of turkey sera from five separate flocks indicated natural infection with the paramyxovirus to be relatively widespread. experimental infection of turkeys produced only mild resp ... | 1979 | 523797 |
| lesions in lambs experimentally infected with bovine respiratory syncytial virus. | respiratory syncytial virus was inoculated intratracheally into five 1-week-old lambs. three of the lambs responded clinically with fever, hyperpnea, and listlessness. pulmonary lesions consisted of multifocal areas of consolidation, with necrosis of individual epithelial cells of the airways and accumulation of necrotic debris, macrophages, and few neutrophils in terminal airways and alveoli. pulmonary septa in affected areas were infiltrated with numerous macrophages and lymphocytes. viral par ... | 1979 | 525867 |
| experimental respiratory syncytial virus infection in feeder-age lambs. | signs of disease, lesions, and serologic response were seen in six 6-month-old-lambs experimentally inoculated with respiratory syncytial virus (rsv). a transient febrile response, mild hyperpnea, and listlessness were seen. multifocal areas of interstitial pneumonia and bronchiolitis were seen in lambs necropsied during the period of clinical response. a serologic response to rsv was seen in all lambs, and rsv was recovered from five lambs. | 1979 | 525890 |

| respiratory syncytial virus infection in inbred mice. | respiratory syncytial virus infected the nose and lungs of each of 20 strains of inbred mice, with viral titers varying 100-fold from least permissive to most permissive strains. viral titers appeared to be under genetic control, but did not correlate with the h-2 haplotype. | 1979 | 546793 |
| incidence of rs virus infections in premature children's ward. | in the course of two years (1974-76) four outbreaks of acute respiratory disease in the premature children's ward of a prague hospital were studied virologically and clinically. rs virus (rsv) was found to be the aetiological agent. the highest isolation rate of rsv was achieved when using two heteroploid cell lines (l-132 and hep-2 cells) simultaneously. of the 30 children examined, 60% showed a severe course of disease (pneumonia and/or bronchiolitis) while in 40% of the children the disease h ... | 1979 | 575897 |

| study of 8-year-old children with a history of respiratory syncytial virus bronchiolitis in infancy. | thirty-five children known to have had respiratory syncytial virus bronchiolitis in infancy were examined at the age of 8 and their respiratory function tested. the results were compared with those in 35 controls matched for age, sex, and social class. although 18 of the children who had had bronchiolitis in infancy had experienced subsequent episodes of wheezing, these were neither severe nor frequent in most cases and had apparently ceased by the age of 8. nevertheless, the mean exercise bronc ... | 1978 | 620129 |

| interferon in nasal secretions from infants with viral respiratory tract infections. | interferon levels in nasal secretions of infants under one year of age, and hospitalized with lower repiratory tract disease, were measured during two respiratory infection seasons. in the first year serial secretions from 50 infants with respiratory syncytial virus infection were examined. undetectable or low levels of interferon were found in all samples, and mean levels did not fluctuate significantly in relation to disease and recovery. this was in contrast to anti-rsv iga, which appeared an ... | 1978 | 650342 |
