Eight strains of anaerobic Gram-negative bacilli isolated from infections of the skin and soft tissues were subjected to a comprehensive range of phenotypic and genotypic tests. 16S rRNA gene sequence analysis revealed the strains to constitute a homogeneous group, distinct from species with validly published names but related to a cluster including Prevotella buccae, Prevotella dentalis and Prevotella baroniae. A novel species, Prevotella bergensis sp. nov., is proposed to accommodate these strains. Prevotella bergensis is saccharolytic and produces acetic and succinic acids as end products of fermentation. The G+C content of the DNA of the type strain is 48 mol%. The type strain of Prevotella bergensis is 94067913T (=DSM 17361T=CCUG 51224T).
Published online ahead of print on 2 December 2005 as DOI 10.1099/ijs.0.63888-0.
The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of P. bergensis DSM 17361T is AY350613.
Electron micrographs of P. bergensis, an extended phylogenetic tree and FAME analyses compared with other Prevotella species are available as supplementary material in IJSEM Online.
