Neighbor-joining tree representing full-length SGA env sequences for ZM247F. Blue and red sequences represent the env SGA sequences from acutely infected ZM247F (blue) and superinfected (red) viral sequences. Black sequences are derived from ZM247M, the epidemiologically unlinked chronically infected partner. Bootstrap values > 80 are considered statistically significant. Sequences denoted by circles indicate the parental sequences (blue, red circle), and stars denote potential recombinant daughter sequences (purple stars) that were used for recombination analyses (below).
