Figure 3. Phylogenetic tree based on a comparison of the 16 S rRNA gene sequence. The phylogenetic tree was generated using the neighbor-joining method. Bootstrap values, expressed as percentages of 1000 replications, are given at branching points. Bar shows 10 nucleotides substitutions per 1000 nucleotides.
