Phylogenetic analysis based on the complete genome (11, 700 nucleotides). The nucleotide sequences were analyzed using a MEGA 4.0 package. The phylogenetic tree was constructed by Neighbor-joining cluster analysis with the bootstrap option. The numbers at the branching points are bootstrap values estimated with 1,000 pseudo-replicate data. The last numbers of each strain name indicate the year of isolation. The locations are shown to the left of the strain name. GenBank Accession numbers are given in parentheses.
