Figure 1. Phylogenetic reconstruction of SIV env of plasma and CSF sequences from morphine-dependent and control macaques infected with SHIVKU-1B, SHIV 89.6P, and SIV/17 E-Fr.

Figure 1

DNA sequences were derived from RT-PCR of viral RNA extractions from plasma (solid symbols) and CSF (open symbols) at weeks 12 (circles) and 18 (triangles) post-infection. The phylogenetic trees were generated by the neighbor-joining method using the MEGA 3.1 program. The trees were rooted using the corresponding sequence from SIV/17E-Fr env (□). All trees are drawn to the same scale. The distance scale is indicated in the lower right of the figure.
