FIG 6.

Amino acid alignment of gI consensus sequences from HSV-2, the HSV-2 African subset identified in Fig. 2, and HSV-1. The amino acids are colored according to a polarity scale (yellow, nonpolar; green, polar/uncharged; red, polar/acidic; blue, polar/basic). The dashes represent gaps inserted to maximize the alignment. The boxes indicate differences from HSV-1 and HSV-2 sequences. The red circles indicate differences between the majority of HSV-2 and the African subgroup.
