Fig. 2From: Full genome characterization of porcine circovirus type 3 isolates reveals the existence of two distinct groups of virus strainsPhylogenetic analysis of PCV3 based on the complete genome of 15 German PCV3 strains (●) and 30 PCV3 reference strains (GenBank accession number, country and year of collection; more details are listed in Additional file 1). The tree was constructed using the neighbor joining method (p-distance model; 1000 bootstraps; only bootstrap values above 50 are shown). The scale bar indicates nucleotide substitutions per siteBack to article page
