Schematic genome comparison. C. ulcerans 0102 (middle) with C. pseudotuberculosis FRC41 (top) and C. diphtheriae NCTC 13129 (bottom) using a BLASTN homology search visualized by the ACT program. The red and blue bars between chromosomal DNA sequences represent individual nucleotide matches in the forward and reverse directions, respectively. BLASTN match scores less than 200 are not shown. A blue box and two yellow boxes represent a tox-positive prophage and other prophages on the chromosome of C. ulcerans 0102, respectively
