Figure. Phylogenic tree of Sapovirus (SaV) sequences isolated
in this study (represented in boldface). SaV nucleotide sequences
were constructed with the partial N-terminal capsid region, using SaV
PEC strain (a porcine SaV) as an outgroup. The numbers on the branches
indicate the bootstrap values for the clusters. Bootstrap values >950
were considered statistically significant for the grouping (8).
Asterisks indicate specimens collected from outpatients. The distance
scale in nucleotide substitutions per position is shown. Sydney isolates
have been deposited in GenBank (accession nos. DQ104357–DQ104363). GenBank
accession numbers for the reference strains are as follows: Arg39, AY289803;
Bristol/98, AJ249939; C12, AY603425; cruise ship/2000, AY289804; Ehime1107,
DQ058829; Houston/27/90, U95644; London/29845/90, U95645; Manchester,
X86560; Mc2, AY237419; Mc10, AY237420; Mex340/1990, AF435812; NK24, AY646856;
Parkville, U73124; PEC, AF182760; Sapporo/82, U65427; Stockholm/318/97,
AF194182; Sakaeo15, AY646855; and SW278, DQ125333.
