| longitudinal study of acute respiratory diseases in rio de janeiro: occurrence of respiratory viruses during four consecutive years. | the occurrence of different viruses in nasopharyngeal secretions from children less than 5 years old with acute respiratory infections (ari) was investigated over a period of 4 years (1982-1985) in rio de janeiro. of the viruses known to be associated with ari, all but influenza c and parainfluenza types 1, 2 and 4 were found. viruses were found more frequently in children attending emergency or pediatric wards than in outpatients. this was clearly related to the high incidence of respiratory sy ... | 1991 | 1668974 |
| antigenic characterization of respiratory syncytial virus group a and b isolates in rio de janeiro, brazil. | the antigenic characteristics of 87 strains of respiratory syncytial virus isolated in rio de janeiro, brazil, from 1982 to 1988 were determined with a panel of monoclonal antibodies (mabs) in an enzyme immunoassay. four of these mabs immunoprecipitated the fusion protein, and five immunoprecipitated the large glycoprotein. on the basis of the patterns of reaction of these mabs to respiratory syncytial virus isolates in an enzyme immunoassay, we were able to separate isolates into the two major ... | 1991 | 2037672 |

| etiology of acute respiratory tract infections among children in a combined community and hospital study in rio de janeiro. | we reviewed data collected between january 1987 and december 1989 on the etiology of acute respiratory infections (ari) among 827 children in two low-income communities and a hospital in rio de janeiro. respiratory syncytial virus was identified in 38% of cases of ari, influenza a virus in 1%, parainfluenza 3 virus in 1%, and multiple viruses in 1%. respiratory syncytial virus was most prevalent among hospitalized children, with seasonal increases in the late fall and winter. the principal bacte ... | 1995 | 7795085 |
| [respiratory syncytial virus -- associated lower respiratory tract infections in hospitalized infants]. | for analysis of clinical features and outcome of hospitalized infants with respiratory syncytial virus lower respiratory tract infection, was carried out. cross-sectional study with 89 infants, hospitalized in two public hospitals during the 1997 and 1998 rsv seasons, in rio de janeiro city. nasopharyngeal secretions were obtained and specimens processed for viral antigens detection by indirect immunofluorescence assay with the use of anti rsv, anti-influenza a and b and anti parainfluenza type ... | 2005 | 15717087 |
| acute respiratory viral infections in children in rio de janeiro and teresópolis, brazil. | the frequency of viral pathogens causing respiratory infections in children in the cities of rio de janeiro and teresópolis was investigated. nasal swabs from children with acute respiratory illnesses were collected between march 2006 and october 2007. specimens were tested for viral detection by conventional (rt)-pcr and/or real time pcr. of the 205 nasal swabs tested, 64 (31.2%) were positive for at least one of the viral pathogens. single infections were detected in 56 samples, 50 of those we ... | 2012 | 22983287 |
