From: Typing Clostridium difficile strains based on tandem repeat sequences
Phylogenetic analysis (neighbor joining) based on the repeat successions in concatenated TR6 and TR10 sequences from 154 C. difficile isolates. The repeat-distance matrix was calculated based on the DSI model, which considers repeat substitutions, insertions, deletions, and duplications (see Methods; [47]). Corresponding ribotypes, TRST types, and MLST sequence types are indicated.
