Genotypic characterization of human immunodeficiency virus type 1 in Greece. Multicentre Study on HIV-1 Heterogeneity.

abstract：:To better understand the emergence of HIV-1 variants in Barbados and the association with transmission modes, we analyzed phylogenetic relationships and genetic variability among HIV-1 strains collected in 1996 from 36 antiretroviral therapy-naive patients. Only subtype B variants were present in this sampling, based ...
