Fig 1. ML trees of sequences of HIV-1 isolates from databases (all from Portugal) or obtained by us (from Spain) clustering with the BG recombinant virus 9196_01 in (a) PR-RT and/or the (b) V3 region.
Sequences obtained in this study are in bold type. HXB2 positions delimiting the analyzed segments are in parentheses. Countries of collection of database viruses of subtype G in PR-RT and of subtype B in V3 are indicated with the two-letter ISO code. Only bootstrap values ≥70% are shown.
