ParasutterellaRANK: GenusTAXONOMY: cellular organisms -> Bacteria -> Proteobacteria -> Betaproteobacteria -> Burkholderiales -> Sutterellaceae -> Parasutterella OVERVIEW: Parasutterella is a genus of Gram-negative, strictly anaerobic, nonspore-forming bacteria from the family Sutterellaceae isolated from human faeces. On the basis of 16S rRNA gene sequence analysis, species of the genera Sutterella and Parasutterella form a distinct and deep evolutionary lineage of descent in the order Burkholderiales. This lineage could not be associated with any of the four known families of the order Burkholderiales. The distinct phylogenetic position and the unusual combination of chemotaxonomic characteristics shared by these genera, such as the predominant quinones and cellular fatty acid compositions, suggest that they constitute a novel family in the order Burkholderiales, for which the name Sutterellaceae fam. nov. is proposed to accommodate the genera Sutterella and Parasutterella. [PMID: 20400667] Cells are Gram-negative, non-motile, strictly anaerobic, non-spore-forming cocci to coccobacilli. Oxidase-, urease and catalase-negative. Asaccharolytic. Grow in the presence of bile. Aesculin and gelatin are not hydrolysed and nitrate is not reduced. Indole is not produced. The main respiratory quinones are MK-6 and MMK-6. The only major fatty acid (.10 % of the total) is C18 : 1v9c. The type species is Parasutterella excrementihominis. This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072]
