Phylogenetic tree constructed using sequences of the 16S rRNA gene of <i>C. concisus</i> strains from UC and controls and other strains available in GenBank.

<p>Strains from UC are underlined in red and those from HC are underlined in blue. The evolutionary history was inferred using the Neighbor-Joining method. The bootstrap consensus tree inferred from 500 replicates was taken to represent the evolutionary history of the taxa analysed. The evolutionary distances were computed using the Maximum Composite Likelihood method.
