Figure 1From: Transmission of new CRF07_BC Strains with 7 amino acid deletion in Gag p6Phylogenetic tree constructed with 98 Chinese-derived HIV-1 BC recombinant gag sequences from HIV database. The neighbor-joining tree was constructed by Mega4.0. CRF07_BC strains forms an independent cluster and P6Δ7 strains were all clustered within CRF07_BC strains. ▲represents P6Δ7 strains.Back to article page
