Parabacteroides is a Gram-negative, anaerobic, non-spore-forming genus from the family Tannerellaceae.[2][3][4][5]
First isolated from fecal specimen in 1933, type strain Parabacteroides distasonis was originally classified under the name Bacteroides distasonis.[6] The strain was re-classified to form the new genus Parabacteroides in 2006.[7] Parabacteroides currently comprise 21 phylogenetically, ecologically, and metabolically diverse species, 11 of which are listed in the taxonomic database List of Prokaryotic names with Standing in Nomenclature (LPSN) as validly published.[2]
Within the Parabacteroides genus, species P. distasonis and P. goldsteinii have been associated with beneficial effects in human health, relating to their integral role in gut microbiota along the digestive tract.[8][9][10]
The taxon ID number used for prokaryotic genus Parabacteroides is 516255.[2] Parent taxon comes from bacterial family Tannerellaceae, identified by number 29533 in the online LPSN database.[2]
Genomics
The genomes of Parabacteroides are highly variable, both across species and within a single strain. For example, genomes isolated from type strain P. distasonis range in size from approximately 4.5 to 5.2 Mb (megabases) and encode over 2,000 functional proteins, signifying substantial variation within the species.[11]
