| 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 |
