Bacteroides ureolyticus

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.

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]
