Phylogenetic analysis of BTV-3 variant found in livestock in the Netherlands, September 2023. Trees were obtained by using the maximum-likelihood method. A) Initial phylogenetic comparison of genome segment 2 sequence of the emerging BTV-3/NET2023 variant from the Netherlands with segment 2 sequences from notifiable BTV reference strain serotypes 1–24. B) Available and closely related genome segment 2 sequences from different BTV-3 strains selected for detailed phylogenetic analysis. Unrooted tree branches have bootstrap values indicated at the nodes. GenBank accession numbers are included in sequence names. Scale bars indicate nucleotide substitutions per site. BTV, bluetongue virus; BTV-3, BTV serotype 3.
