Figure 5

Maximum-likelihood phylogenetic tree of 41 complete Ross River virus envelope (E) 3 and E2 gene nucleotide sequences (1,458 nt), 32 from isolates collected in Queensland and New South Wales, Australia, during January 1, 1990–June 30, 2015 (gray shading), and 9 reference sequences. Tree was constructed by using MEGA 7.0 (https://megasoftware.net) with bootstrap support (1,000 replications). The tree is midpoint rooted for clarity. Circulating northeastern lineages I and II are shown together with sublineages Ia and Ib. Percentage bootstrap support values determined from 1,000 replicates are shown for key nodes. GenBank accession numbers are provided. Scale bar indicates nucleotide substitutions per site.
