From: Phylogenomic insights into West Nile virus lineage 2 circulating in Croatia
The phylogenetic analysis of WNV lineage 2 genomic sequences. The maximum-likelihood tree was inferred using IQ-Tree [12]. The numbers located on the branches represent ultrafast bootstrap values (≥ 0.7) [13, 14]. The TN + F + G4 model was applied as the optimal nucleotide substitution model. The dataset included sequences from Croatia (generated in this study), WNV lineage 2 sequences from the BV-BRC database isolated from human samples from Europe and sequences from GenBank for specific lineages and clades. The tree was rooted using WNV genomes EF429198 and EF429197 as outgroups. WNV genome sequences are annotated with GenBank accession numbers, country of origin, clades and sublineages [20, 21].
