| 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 subgroup a over a six-year period (1999-2004) in argentina. | human respiratory syncytial virus (hrsv) is the main viral cause of acute lower respiratory tract infections in children. little information about the molecular epidemiology of hrsv in developing countries, such as argentina, is available. by rt-pcr, we subgrouped 353 hrsv isolates over six consecutive epidemic seasons (1999-2004) and few isolates from 1997. between them, 232 (65.7%) belonged to subgroup a and 121 (34.3%) to subgroup b. therefore, the nucleotide, amino-acid variability and phylo ... | 2005 | 16121371 |
