Sequence alignment analysis in the helix 25 within 23S rRNA gene sequences from Campylobacter isolates. Numbers at the left and right refer to the nucleotide positions determined in the present study. Dots indicate identical bases; changes are explicitly indicated: dashes are deletions; identical positions in all cases are marked by asterisks. Nucleotide sequence data in the helix 25 region within the rrnB operon from the Escherichia coli strain (J01695), identified to lack IVSs, were also aligned for comparison. C. sp, C. sputorum
