Anaerococcus degenerii sp. nov., isolated from human clinical specimens

• The description of a novel Anaerococcus sp.
• Proposed name: Anaerococcus degenerii.
• Homogeneous phenotypic and genotypic cluster.

Four clinical isolates of gram-positive strict anaerobic cocci were isolated from four different human mixed anaerobic infections. The taxonomical status of the four strains could not be established using standard identification techniques. The biochemical features of the strains were established and their taxonomic position was determined using 16S rRNA sequencing. The four strains form a homogeneous phenotypical and genotypical cluster. A new Anaerococcus species is proposed for these isolates: Anaerococcus degenerii sp. nov. The type strain is UMCG-104T = DSM29674T (accession number AM176528).
