Fig. 5From: First description of clinical presentation of piscine orthoreovirus (PRV) infections in salmonid aquaculture in Chile and identification of a second genotype (Genotype II) of PRVPhylogenetic tree of segment S1 sequences from PRV isolates from Norway, Chile, and Canada. The phylogenetic tree was constructed using the Maximum Likelihood method (software package: PhyML 3.0) [53]. An outgroup (Genbank accession number: AF059720) was used to determine its root, but the outgroup itself was not included in the tree. The bootstrapping procedure was applied for 1000 times and the branches with 60Â % or higher bootstrapping support values were markedBack to article page
