Figure 2. Phylogenetic analysis of the polymerase region (A) and the capsid region (B), showing the different genogroups (GI–GV). The sapovirus (SaV) isolates detected in the study are highlighted in boldface. The scale indicates nucleotide substitutions per position. The numbers in the branches indicate the bootstrap values. GenBank accession numbers of reference strains are as follows: C12 (AY603425), Mc10 (AY237420), Kushiro5 (AB455793), Mc2 (AY237419), Bristol (AJ249939), Dresden (AY694184), NK24 (AY646856), Ehime1107 (DQ058829), Yak2 (AB046353), and Yokohama/16/2007/JP (AB305049).
