TAXONOMY: Bacteroidetes/Chlorobi group -> Bacteroidetes -> Bacteroidia -> Bacteroidales -> Porphyromonadaceae -> Parabacteroides -> Parabacteroides merdae
This genus is closely related to the genus Bacteroides. These genera constitute the most abundant members of the intestinal microflora of mammals. Typically they are symbionts, but they can become opportunistic pathogens in the peritoneal (intra-abdominal) cavity. These organisms produce many extracellular enzymes which assist in the breakdown of complex plant polysaccharides such as cellulose and hemicellulose and host-derived polysaccharides such as mucopolysaccharides.Parabacteroides merdae. Parabacteroides merdae is part of normal human gut flora. In one comprehensive 16S rDNA sequence-based enumeration of the colonic microbiota of three healthy adult humans it represents, on average, 0.262% of all 16S rDNA sequences and 0.550% of the sequences in its division (Eckburg et. al. (2005)).
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]
Identified as a 'core species' of the human gut microbiome. [PMID: 23222524]
|COGEM||COGEM released a comprehensive database of pathogenicity assessment of around 2575 bacterial species in 2011. The database ranks the pathogenicity of species on a scale of 1 to 4. Parabacteroides merdae ranks on this scale: |
