Overview

  • Rossellomorea aquimaris, (aka Bacillus aquimaris), is a Gram-variable, spore-forming, strictly aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 38%. Rossellomorea aquimaris is likely to be transient and not a long-term gut coloniser. (Yoon2003)



  • This organism has been recovered from tidal flats from Korea and has been detected in human faeces (Bilen2018e). 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.
