Ruminococcus gnavus
Description and Significance
Ruminococcus gnavus is a Gram-positive obligate anaerobe bacterium discovered first in the human gastrointestinal tract. Despite its name it is actually a part of the genus Mediterraneibacter, although retaining its Ruminococcus name for study purposes.
R. gnavus is considered a part of the normal human gut microbiome in children and adults. It has been suggested that it has a role in priming the gut microbiota in association with standard weight gain velocity in infants.
Ruminococcus gnavus is one of few micorbiota bacterium that persists at a consistent level from infancy to throughout adulthood. Studies have shown that R.gnavus is a key biomarker of health and diseases with certain immune/metabolic properties, making it an important bacterium to understand.
