Phylogenetic analysis of Usutu virus strains. Phylogenetic tree based on the partial NS5 gene and showing positioning of the USUV isolates used in this study (in blue). USUV sequences are labeled with their respective ID or GenBank accession number, preceded by country and year of isolation. Scale bar indicates mean number of nt substitutions per site. The analysis was processed through on line phylogeny analysis (http://www.phylogeny.fr; Réseau National des Génopoles), and tree was rooted with an USUV Africa 1 sequence as the outgroup virus (GenBank accession number KC754958). The asterisks (*) at major nodes indicate an SH-like support value > 70%
