Overview


  • Ruminococcus gauvreauii is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, coccus bacterium. It has been detected in at least 6 gut microbiome compilation studies or metastudies. Ruminococcus gauvreauii is probably a common, although minor, coloniser of the gut. (Domingo2008; Togo2018)



  • This organism has been recovered from human faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal. Robust growth can have positive consequences for gut health.

  • All ruminococci require fermentable carbohydrates for growth, and their substrate preferences appear to be based on the diet of their particular host. Most ruminococci that have been studied are those capable of degrading cellulose, much less is known about non-cellulolytic non-ruminant-associated species, and even less is known about the environmental distribution of ruminococci as a whole.

    Ruminococcus species are defined as strictly anaerobic, Gram-positive, non-motile cocci that do not produce endospores and require fermentable carbohydrates for growth (Rainey, 2009b). They were initially described from the isolation of Ruminococcus flavefaciens from the bovine rumen (Sijpesteijn, 1948). Ruminococcus is currently considered a polyphyletic genus, with species members belonging to two separate families: the Ruminococcaceae and the Lachnospiraceae (Rainey & Janssen, 1995). Ruminococcus species are predominantly associated with herbivores and omnivores, relative to carnivores, and that significantly abundant Ruminococcus populations are absent in non-host-associated environments.
