Roseburia

Roseburia is a genus of butyrate-producing, Gram-positive anaerobic bacteria that inhabit the human colon. With a cell morphology of a curved-rod shape, this bacterium uses its flagella to move around. The bacterium is named in honor of Theodor Rosebury who has contributed vastly to the oral microbiome field. First isolated in human fecal samples, Roseburia has been found to provide several health benefits pertaining to the human gut microbiome. Belonging to the Bacillota phylum (previously known as Firmicutes), Clostridia class, Clostridiales order, and Lachnospiraceae family, the Roseburia genus currently has 5 known species: Roseburia cecicola, Roseburia faecis, Roseburia hominis, Roseburia intestinalis, and Roseburia inulinivorans.

There are several diseases that Roseburia has been shown to have a positive effect on such as inflammatory bowel disease, alcoholic fatty liver, colorectal cancer, metabolic syndrome and muscle metabolism. Increased abundance of Roseburia is associated with weight loss and reduced glucose intolerance in mice.
