Phylogenetic relationships of SMC-7485 and other Mycobacterium species based on ITS sequences, which were retrieved from GenBank database. This tree was generated by the neighbor-joining method. Mycobacterium vaccae DSM 43292 was used as an outlier. Numbers at branching nodes are percentages of 1,000 bootstrap replications. Only values greater than 50% are shown. In this tree, M. senegalense strains are separated into two subgroups.
