Phylogenetic maximum likelihood tree based on partial NS4B-coding nucleotide sequence and complete-coding sequences of NS5 protein of Usutu virus (nucleotide positions 7372–10,398 according to complete genome sequence of Vienna strain, AY453411). Sequence Africa 1, AY453412 was used as the outgroup. The code of the sequences consists of GenBank accession number, place and year of origin. The sequences obtained in this study are indicated by bold; individual geographical lineages are color-coded). The tree was generated using the GTR+I+G substitution model and 1000 replicates bootstrap analysis. Nodes with bootstrap support of <50% are indicated by asterisk. The lengths of tree branches correspond to the number of substitutions per site.
