| molecular epidemiology of respiratory syncytial virus infections among children with acute respiratory symptoms in a community over three seasons. | to study the molecular epidemiology of respiratory syncytial virus (rsv) in a community, children with acute respiratory symptoms at a pediatric outpatient clinic in niigata, japan, were analyzed over three seasons from november 2001 to july 2004. of 499 nasopharyngeal aspirate specimens, 185 (37.1%) were rsv positive, and only 8 (4.5%) of 177 patients were shown by the reverse transcription (rt)-pcr method to be reinfected. rsv infection occurred beginning in the early winter, and the rates dec ... | 2005 | 15634948 |
| emerging genotypes of human respiratory syncytial virus subgroup a among patients in japan. | human respiratory syncytial virus (hrsv) is a common etiological agent of acute lower respiratory tract disease in infants. we report the molecular epidemiology of hrsv in niigata, japan, over six successive seasons (from 2001 to 2007) and the emerging genotypes of hrsv subgroup a (hrsv-a) strains. a total of 488 hrsv samples were obtained from 1,103 screened cases in a pediatric clinic in niigata. according to the phylogenetic analysis, among the pcr-positive samples, 338 hrsv-a strains cluster ... | 2009 | 19553576 |
