Neighbor-joining tree based on the comparison of 23 S rRNA gene sequences. This phylogenetic tree comprises 23 S rRNA amplicons obtained in the 1st genus Helicobacter-specific PCR of the nested 23 S rRNA PCR and relevant GenBank reference sequences. Eight amplicon sequences were left out of this analysis because sequencing yielded an amplicon that was too short for multiple sequence alignment. Sample names include the number assigned to the animal, followed by C or D (= cat or dog) and A or C (= antrum or corpus). Reference sequence names include the Helicobacter species, strain, accession number between brackets and host where possible.
