Overview

  • Nevskia ramosa is a Gram-negative, non-spore-forming, strictly aerobic, gliding, bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 67.8%. Nevskia ramosa is likely to be transient and not a long-term gut coloniser. (Kim2011b; Babenzien2005Bergey)



  • This organism has been recovered from human faeces, and aquatic sources. 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. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Optimum growth temp is low (20-25C), so unlikely to be a gut coloniser.
