Christensenella

Christensenella is a genus of non-spore-forming, anaerobic, and nonmotile bacteria from the family Christensenellaceae. The species "C. minuta" has been published and validated, and "C. timonensis" and "C. massiliensis" have been proposed as novel species of the genus "Christensenella", all isolated from human feces. "C. minuta" in the gut has been associated with reduction in body weight and adiposity of mice. In a test on 977 volunteers, humans with higher levels of "Christensenella" in their guts were found to be more likely to have a lower body mass index than those with low levels. "Christensenella" are better represented in persons who are metabolically healthy.
