| identification of viruses in a study of acute respiratory tract infection in children from uruguay. | for the purpose of identifying viral agents associated with acute respiratory tract infections (ari) in children less than 5 years old, a longitudinal community study was undertaken in montevideo, uruguay, from may 1985 to december 1987. this report includes results obtained by cell culture and immunofluorescence techniques for detection of respiratory syncytial virus (rsv), influenza a and b viruses, parainfluenza 1 and 3 viruses, and adenovirus. two populations were studied: children visited a ... | 1990 | 2270420 |
| acute respiratory infections in children from a deprived urban population from uruguay. | to obtain base line data on incidence, duration, clinical characteristics and etiology of acute respiratory infections (ari), 276 children from deprived families living in montevideo were followed during 32 months. the target population was divided into two groups for the analysis of the results: children aged less than 12 months and those older than this age. during the follow-up period 1.056 ari episodes were recorded. ari incidence was 5.2 per child/year. it was 87% higher in infants than in ... | 1994 | 7997774 |
| evolutionary pattern of human respiratory syncytial virus (subgroup a): cocirculating lineages and correlation of genetic and antigenic changes in the g glycoprotein. | the genetic and antigenic variability of the g glycoproteins from 76 human respiratory syncytial (rs) viruses (subgroup a) isolated during six consecutive epidemics in either montevideo, uruguay, or madrid, spain, have been analyzed. genetic diversity was evaluated for all viruses by the rnase a mismatch cleavage method and for selected strains by dideoxy sequencing. the sequences reported here were added to those published for six isolates from birmingham, united kingdom, and for two reference ... | 1994 | 8057427 |
| antigenic and genetic variability of human respiratory syncytial viruses (group a) isolated in uruguay and argentina: 1993-2001. | the antigenic and genetic diversity of g glycoprotein from 25 human respiratory viruses (group a) isolated during nine consecutive epidemics (1993-2001) in montevideo, uruguay, and 7 strains isolated in buenos aires, argentina, in the same period were analyzed. genetic variability was evaluated by partial sequence of the g protein gene. phylogenetic analysis indicated that most uruguayan and argentinean group a isolates clustered into three genotypes: ga5, ga2, and ga1. some strains clustered in ... | 2003 | 12938207 |
| molecular epidemiology of human respiratory syncytial virus in uruguay: 1985-2001--a review. | the variability of the g glycoprotein from human respiratory syncytial viruses (hrsv) (groups a and b) isolated during 17 consecutive epidemics in montevideo, uruguay have been analyzed. several annual epidemics were studied, where strains from groups a and b circulated together throughout the epidemics with predominance of one of them. usually, group a predominates, but in some epidemics group b is more frequently detected. to analyse the antigenic diversity of the strains, extracts of cells in ... | 2005 | 16113858 |
| molecular detection and genetic variability of human metapneumovirus in uruguay. | human metapneumovirus (hmpv) has been described as circulating among the uruguayan population at least since 1998 based on serologic evidence. however, no isolation attempts, molecular detection, or genetic studies have been carried out so far in the country. in the present study, molecular detection of circulating hmpv in children hospitalized with acute respiratory tract infection in montevideo-uruguay was carried out by reverse transcription-polymerase chain reaction (rt-pcr) amplification of ... | 2010 | 20336730 |
