Overview

  • Barnesiella viscericola is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 52.0%. Barnesiella viscericola is probably a rare gut coloniser. (Sakamoto2007; Editorial2011gBergey)



  • This organism has been recovered from caeca of chickens and human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal.

    The type strain of Barnesiella viscericola is C46T (=JCM 13660T=DSM 18177T). The strains were isolated from chicken caecum. The strains were found to be obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative rods. [PMID: 17267976]
