Figure 2

Phylogeny of WNV lineage 2 in Europe and Africa. The neighbor-joining tree was generated from an alignment of complete WNV genomes (10,350 base pairs) using MEGA 5 software. Each sequence identifier represents the country of origin and the year of isolation. Further details on each virus are provided in Table 2. Bootstrap values are shown at key nodes and were derived from 1000 replicates. The divergent virus MAD-78 is used as an outgroup.
