Six strains of anaerobic, Gram-negative coccobacilli isolated from the root canals of patients with endodontic infections (five strains) and from a deep periodontal pocket (one strain) were subjected to a comprehensive range of phenotypic and genetic tests and were found to comprise a homogeneous group. Following 16S rRNA gene sequence analysis, they were found to be most closely related to Dialister pneumosintes, with 93 % sequence similarity between the two taxa. A novel species, Dialister invisus sp. nov., is proposed. Biochemically, the species is largely unreactive and is asaccharolytic, with only traces of acetate and propionate detected as metabolic end-products. The G+C content of the DNA of D. invisus strains is 45–46 mol%. The type strain is E7.25^T (=CCUG 47026^T=DSM 15470^T).

Published online ahead of print on 4 July 2003 as DOI 10.1099/ijs.0.02640-0.

The GenBank accession number for the 16S rRNA gene sequence of Dialister invisus E7.25^T is AY162469.
