Figure 6. Maximum clade credibility tree based on segment 10 of LNV-1 and LNV-2 prototype isolates and including the 27 LNV isolates obtained from mosquitoes in 2005.

The axis shows the estimated dates for most recent common ancestors as years before 2005. NE-9712 (LNV-NE9712) and NE-9731 (LNV-NE9731) are prototype strains of LNV serotypes 1 and 2, respectively. Values at the nodes are those for the most recent common ancestor of segment 10.
