Phylogenetic position of Caminibacter mediatlanticus strain TB-2T relative to type strains of Epsilonproteobacteria isolated from deep-sea hydrothermal vents. Sequences were aligned automatically using CLUSTAL X and the alignment was manually refined using SEAVIEW [10,11]. Neighbor-joining trees were constructed with Phylo_Win, using the Jukes-Cantor correction . Bootstrap values (>50%) based on 500 replications. Bar, 0.02 substitutions per nucleotide position.
