They are non-saccharolytic, use peptone as a major energy source and produce butyrate.
Clinical relevance
This genus is part of the vaginal and gut microbiota.
They have been reported to as present in diabetic skin and soft tissue infections, bone and joint infections, surgical site infections, chorioamnionitis and bloodstream infections.
They are typically found as part of polymicrobial infections but are difficult to recover with usual clinical cultures. They have been increasingly reported with the more widespread use of
