Figure 4

Phylogenetic tree of segment 5 sequences from selected ISAV isolates of European genotype. The analysis was performed using 808 nucleotides of the 5′ portion of the F gene (excluding the nucleotides responsible for Q266 → L266 substitution). The phylogenetic tree was constructed by maximum likelihood using the neighbor-joining method and Tamura-Nei genetic distances. All ISAV-HPR7a and HPR7b viruses associated with the 2014 ISA outbreaks in Chile are shown in bold.
