Alistipes putredinisRANK: SpeciesTAXONOMY: Bacteroidetes/Chlorobi group -> Bacteroidetes -> Bacteroidia -> Bacteroidales -> Rikenellaceae -> Alistipes -> Alistipes putredinis OVERVIEW: Alistipes putredinis (GenBank Accession Number for 16S rDNA gene: L16497) is a member of the Bacteroidetes division of the domain bacteria and has been isolated from human feces. It has been found in 16S rDNA sequence-based enumerations of the colonic microbiota of adult humans (Eckburg et. al. (2005), Ley et. al. (2006)). The sequenced strain was obtained from Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSMZ) (DSM# 17216). This is from the Human Microbiome Initiative. A species isolated from feces, cases of acute appendicitis, and abdominal and rectal abscesses; also from foot rot of sheep and from farm soil. Its properties are divergent from most Bacteroides species. Three members of the Bacteroidetes, Bacteroides uniformis, Parabacteroides merdae, and Alistipes putredinis positively correlated with cecal acetate, propionate and butyrate levels. Whereas members of these species generate acetate and propionate, their ability to produce butyrate has not been reported. Their positive association with butyrate levels could be due to interspecies acetate cross-feeding with butyrate-producing taxa. [PMC 3829625] Alistipes is a bile tolerant organism. Synonym: Bacteroides putredinis 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]
