Parasutterella secundaRANK: SpeciesTAXONOMY: Bacteria -> Proteobacteria -> Betaproteobacteria -> Burkholderiales -> Sutterellaceae -> Parasutterella -> Parasutterella secunda OVERVIEW: A novel, strictly anaerobic, non-spore-forming, Gram-reaction-negative coccobacillus bacterium, designated strain YIT 12071(T), was isolated from human faeces. Biochemically, this strain was largely unreactive and asaccharolytic. Growth of this strain in peptone-yeast-extract broth was weak, producing no visible turbidity, and no short-chain fatty acids were detected as an end product of metabolism. Following 16S rRNA gene sequence analysis, strain YIT 12071(T) was found to be most closely related to Parasutterella excrementihominis (90 % sequence similarity) and phylogenetically distinct from other known genera belonging to the order Burkholderiales. Biochemical data supported the affiliation of this strain with the genus Parasutterella. Strain YIT 12071(T), therefore, represents a novel species of the genus Parasutterella, for which the name Parasutterella secunda sp. nov. is proposed. The type strain is YIT 12071(T) (=DSM 22575(T) =JCM 16078(T)). [PMID: 20400667] Parasutterella secunda is a Gram-negative, nonsaccharolytic, strictly anaerobic, nonspore-forming, nonmotile bacterium of the genus Parasutterella in the family Sutterellaceae, isolated from human faeces. Colonies of Parasutterella secunda are translucent to beige colored. This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072] |
