Rooted single gene maximum likelihood dendrogram based on tcuC from Helicobacter and Campylobacter. The chelonian- and squamate-associated strains are indicated with a chelonian or lizard, respectively. Enterobacter asburiae L1 was used as outgroup and root. Bootstrap values (≥70%) based on 500 repetitions are shown at the nodes of the dendrogram.
