Phylogenetic analysis of species of the meso-diaminopimelic acid-containing genera Brevibacterium and Dermabacter.

16S rRNA gene sequencing studies were performed on Dermabacter hominis and four meso-diaminopimelic acid-containing species of the genus Brevibacterium. Phylogenetic analysis revealed a close association between Dermabacter hominis and representatives of the lysine-containing genera Arthrobacter, Micrococcus, and Renibacterium. By contrast, the genus Brevibacterium formed a distinct line of descent within the high-guanine-plus-cytosine-containing actinomycetes, displaying no specific affinity with any other organism examined.
