Prevotella maculosa sp. nov., isolated from the human oral cavity

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).
