Southern blot hybridization of a 1200-bp PCR product of genus-specific Helicobacter sp.–positive gallbladder and bile samples and control tissues. Lanes 1–4, gallbladder tissue; lanes 7–10, bile samples that were PCR positive for Helicobacter sp. and identified by sequence analysis. Lane 12, positive control; lanes 5 and 6, control gallbladder; lane 11, control bile; lane 13, reagent control.

Phylogenetic tree constructed on the basis of 16S rRNA sequence similarity values using neighbor joining. Scale bar indicates a 5% difference in nucleotide sequences as determined by measuring the lengths of the horizontal lines connecting two species. The amplicons sequenced in this study are indicated by arrows.
