FIG. 3.

Comparison of viral sequences from plasma and derived cultured virus from a Fiebig stage II virus isolate (BP00002) from South Africa. The envelope sequence analysis of original plasma and virus cultures from supernatant or PBMCs of original isolate as described in Fig. 2 was carried out on 10–12 separate sequences of the respective virus preparations. Point mutations in each sequence are designated by a color marker to indicate specific mutation type (A). The observed mismatches mostly led to codon changes (B).
