Maximum likelihood phylogenetic tree based on West Nile virus envelope gene sequences, showing the genetic relatedness of viruses infecting mosquitoes in Slovakia to West Nile virus lineage 2 strains, 2018 (n = 27 sequences in tree)
The tree was generated using the Kimura-2 model with bootstrap resampling of 1,000 replicates. The tree is drawn to scale, with branch lengths corresponding to the number of substitutions per site. Bootstrap values are shown at the nodes. GenBank accession numbers of the sequences in the tree are provided and the sequences retrieved in the current study are in bold font and further indicated by black circles.
