Phylogenetic tree of HIV-1 gag p17 region from Italian isolates. The gag p17 region of B as well as non-B clade HIV-1 isolates, identified in the whole epidemic, has been aligned to reference sequences of all Group M subtypes, in order to generate the phylogenetic tree by the neighbor-joining method. The BITindicates the "Italian branch" of the tree; the Italian non-B sequences are individually indicated. The reliability has been estimated from 1’000 bootstrap replicates and only values >90% are shown.
