Fig 3.

Phylogenetic relationships between the Central African E-7 sequences and other E-7 sequences available in GenBank (nt 1 to 413 according to Wallace VP1 numbering). The Central African sequences are indicated by filled circles. For the other sequences, the location and year of isolation are indicated, if known. The percent bootstrap values are indicated if higher than 70. Filled triangles indicate the prototype strains. The E-6 D'Amori sequence was introduced for correct rooting of the tree.
