Three strains of anaerobic Gram-negative bacilli isolated from human oral sites were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group. 16S rRNA gene sequence analysis revealed the strains to constitute a novel group within the genus Prevotella, most closely related to Prevotella oris and Prevotella salivae. A novel species, Prevotella maculosa sp. nov., is proposed to accommodate these strains. Prevotella maculosa 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 maculosa is W1609T (=DSM 19339T =CCUG 54766T).

Abbreviations: FAME, fatty acid methyl ester

The GenBank/EMBL/DDBJ accession numbers for the two 16S rRNA gene sequences obtained from Prevotella maculosa W1609T are EF534314 and EF534315.

An extended phylogenetic tree, a summary of the characteristics of the novel species and a comparison of FAME profiles are available as supplementary material with the online version of this paper.
