If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button.

** Article Draft **[edit]
Parabacteroides is a Gram-negative, anaerobic, non-spore-forming genus from the family Tannerellaceae.[1][2][3][4]
First isolated from fecal specimen in 1933, type strain Parabacteroides distasonis was originally classified under the name Bacteroides distasonis.[5] The strain was re-classified to form the new genus Parabacteroides in 2006.[6] Parabacteroides currently comprise 21 phylogenetically, ecologically, and metabolically diverse species, 11 of which are validly published in the taxonomic database List of Prokaryotic names with Standing in Nomenclature (LPSN).[1]
Within the Parabacteroides genus, species P. distasonis and P. goldsteinii have been associated with both beneficial and pathogenic effects in human health, relating to their integral role in gut microbiota along the digestive tract.[7][8][9]
Taxonomy[edit]
The taxon ID number used for prokaryotic genus Parabacteroides is 516255.[1] Parent taxon comes from bacterial family Tannerellaceae, identified by number 29533 in the online LPSN database.[1]
Genomics[edit]
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.[10]
Species[edit]
The genus Parabacteroides comprises the following species, 11 of which are validly published by the List of Prokaryotic names with Standing in Nomenclature (LPSN): [1]
| Validly Named by the LPSN [1] | Not Validly Named by the LPSN [1] |

Role in the Human Gut Microenvironment[edit]
Part of the bacterial order Bacteroidales present in the human gut, Parabacteroides are commonly found within the gut microenvironment. Parabacteroides species constitute a significant component of microbiota along the digestive tract, benefitting from a commensal relationship with the human body. Intestinal microbiota also benefit the human host, modulating essential metabolism-related processes within the gut microenvironment.[11]
P. distasonis and P. goldsteinii in particular form biofilms in the gut microbiota, allowing these species to survive under harsh conditions and maintain ample populations in extreme pH environments.[7] Recent studies elucidate new applications of Parabacteroides as probiotics, supporting balanced microbiota composition as a benefit to human digestive health.[7] Both P. distasonis and P. goldsteinii exhibit anti-obesity effects via production of secondary bile acids and succinate within the gut microenvironment.[7][9] Studies on Parabacteroides species P. distasonis reveal metabolic benefits of this mechanism, including control of weight gain, decrease in hyperglycemia, and amelioration of hepatic steatosis and other metabolic diseases.
