Thomasclavelia ramosa
Thomasclavelia ramosa is an anaerobic, non-motile, thin, spore-forming, gram-positive bacterium that is among the gut flora of humans. Research 
The bacterium has a possible obesogenic potential but the underlying mechanism of this observed effect in mice are unclear. It is suggested that this microbe under a high-fat diet helps to reinforce the sugar and fat absorption. The associated higher intake of energy-supplying nutrients makes the fat grow faster - a factor of obesity. See also
