FIG. 1.

Neighbor-joining trees of 16S rRNA gene sequences showing the phylogenetic relationships among our clinical isolates and type strains (T) of other Corynebacterium spp. Sequences are indicated with GenBank accession numbers and were trimmed to the length of the shortest sequence. (A) Nearly full length sequences (1,404 nt) showing relationships among a broad distribution of corynebacteria and related species. (B) 5′ 16S sequences (435 nt) showing the ability of partial sequences to differentiate C. falsenii from other clinically important and recently described Corynebacterium species isolates.
