| serologic evaluation of human immunodeficiency virus type 1-infected individuals from argentina and the united states indicates a similar distribution of subgroup b isolates. | utilizing peptides based on the v3 region of gp120, we undertook a serologic examination of human immunodeficiency virus type 1 (hiv-1)-infected individuals from argentina to determine if prevalent hiv-1 isolates could be identified in this population. our findings suggest that a similar pool of hiv-1 subgroup b isolates exists in both argentina and the united states. | 1995 | 7714212 |
| 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 |
| divergent strains of human t-lymphotropic virus type 1 (htlv-1) within the cosmopolitan subtype in argentina. | htlv-1 cosmopolitan subtype transcontinental subgroup a has been described among aboriginal communities from the northwest endemic area of argentina. moreover, transcontinental subgroup a and the japanese subgroup b were reported among blood donors from the nonendemic central region of the country. we carried out the first htlv-1 phylogenetic study in individuals residing in buenos aires capital city. phylogenetic analysis performed on the ltr region showed that all 44 new strains clustered with ... | 2008 | 18834325 |
