Differentiation of viruses in three macaques coinfected with SIVsmE543-3 and SIVsmH635FC. The env V1-V5 region was amplified by RT-PCR from viral RNA isolated from plasma samples of these macaques at 10 days (10d), 8 weeks (8w), 20 weeks, and 26 weeks (H711), 40 weeks (H712), or 27 weeks (H713) postinoculation. PCR products were cloned into plasmids, and the sequences were analyzed. Amino acids at the seven locations which differ between SIVsmE543-3 and SIVsmH635FC in the Env V1-V5 region are shown as described for Fig. 3A. Amino acids that are identical to those of SIVsmE543-3 are shown by white letters in a black background. Amino acids that are identical to those of SIVsmH635FC are shown by black letters in a white background. Amino acid changes other than changes from SIVsmE543-3 and SIVsmH635FC are shaded.
