(a) Maximum Composite Likelihood method and Tamura-Nei matrix model phylogenetic tree based on ORF30 nucleotide sequences. Eighty-two strains including 14 strains isolated in France and Belgium from 2009 to 2018 (red bold text), 67 strains sequenced by Bryant et al. (2018) [14], and reference strain AY665713 (Ab4) are represented in this tree. Dots represent strains with the neuropathogenic type (G₂₂₅₄). Boostrap values after 1000 replication are indicated at major nodes. (b) Median Joining Network based on the same ORF30 nucleotide sequences as for the phylogenetic tree.
