Bacteroides ureolyticus is a species in the bacterial genus of Gram-negative, obligately anaerobic bacteria. Bacteroides species are non-endospore-forming bacilli, and may be either motile or non-motile, depending on the species.[1] The DNA base composition is 40-48% GC. Unusual in bacterial organisms, Bacteroides membranes contain sphingolipids. They also contain meso-diaminopimelic acid in their peptidoglycan layer.

Bacteroides are normally mutualistic, a substantial portion of the mammalian gastrointestinal flora,[2] and they process complex molecules into simpler ones.[3][4][5] As many as 1010-1011 cells per gram of human feces have been reported.[6] They can use simple sugars when available; however, the main sources of energy for Bacteroides species in the gut are complex host-derived and plant glycans.[7]

Pathophysiology

Bacteroides ureolyticus has been isolated from pregnant women with symptoms of bacterial vaginosis.[8]
