Bacteroides vulgatus is generally part of a healthy gut but has been associated with diseases such as Crohn’s disease and inflammation in several other gut diseases.

Taxonomic Level: Species

Family: Bacteroidaceae

Properties: Gram-negative, Anaerobic, Nonsporulating

Additional Information: Some amount of Bacteroides vulgatus in the gut is generally healthy, however many of the known health effects of abnormal levels of this microbe are detrimental. For instance, some studies have implicated E. coli and B. vulgatus in the development of Crohn’s disease, and high levels of B. vulgatus and a related microbe B. dorei have been shown to be associated with inflammation in several gut diseases such as ulcerative colitis, irritable bowel disease, and celiac disease.
