Phylogenetic analysis of complete genome nucleotide sequences of recent WNV-L2 isolates from western-central Europe. Italian clusters were defined by Barzon et al. 2015 [31]. The evolutionary distances were computed using the optimal TN93+G model and the phylogenetic tree was constructed with the Maximum likelihood method. Bootstrap values of major branches are given for 500 replicates. Viral sequences are identified by GenBank accession number, country, and year of isolation. Sequences emphasised in bold and with a black circle (●) were generated during this study.
