FIG. 2.

Phylogenetic trees of Helicobacter using the 16S rRNA gene sequence depict the close relationship of IMM 687835 (arrow) to Helicobacter sp. flexispira taxon 8. The distances between the strains were calculated using the Jukes and Canters algorithm, and the tree was constructed by neighbor-joining analysis. Bootstrap analysis was done with 1,000 resamplings; the percentage is shown at each node. The scale bar represents a 5% difference in the DNA sequence. The accession number for the sequences used in the study are shown in the figure.
