FIG. 1.

Neighbor-joining dendrogram based on 1,311 consecutive positions of the 16S rRNA gene with 1,000 bootstrap replications showing the phylogenetic relationships of T. strandjordae and T. paurometabola (T. inchonensis) ATCC 25938 with other tsukamurellae and select related corynebacterineae of the order Actinomycetales. C. diphtheriae was chosen as the outgroup. Numbers at each node correspond to the bootstrap values. GenBank nucleotide sequence accession numbers are also included for the tsukamurellae. The sequences in GenBank for T. paurometabola ATCC 8368 (accession no. Z46751 and X80628), T. paurometabola ATCC 25938 (accession no. Z36933), and T. inchonensis ATCC 70082 (accession no. X85955) were identical to those generated in this study and were therefore not included in the dendrogram.
