Fig. 3. Neighbour-joining phylogenetic trees of partial segments of recombinant BF viruses from Argentina. Viruses with intersubtype breakpoints in the segments analysed were excluded from each analysis of partial sequences. Nucleotide positions (HXB-2 numeration) that delimit the analysed fragments and the segment number according to Fig. 2 are shown above each tree. Trees are rooted with simian immunodeficiency virus isolate cpzUS. Recombinant BF viruses from Argentina are shown in boldface and F subtype viruses from Brazil are underlined. B subtype viruses from Argentina, sequenced in full-length or partial pol sequences, are marked with an asterisk and subtype reference sequences are indicated with the subtype designation followed by the name of the isolate. Bootstrap values ≥70 % (based on 100 replicates) are shown. The bootstrap value shown in parentheses (b) was obtained after excluding A32878 from the analysis. Relevant clusters including BF recombinants from Argentina and supported by ≥70 % bootstrap values are indicated in square brackets.
