Phylogenetic tree of the full length genomic sequences of 34 sapovirus strains using MEGA 6.

<p>The five strains whose complete genomes were determined in this study are boxed with dotted lines. Among these, the two SaV strains that were newly identified in this study are also indicated with arrows. The number on each branch indicates the bootstrap value. The scale represents the amino acid substitutions per site. Each sapovirus strain is indicated in the following format: Genbank accession number-strain name (species).
