Prevotella bergensis sp. nov., isolated from human infections

Abstract

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).
