Overview

  • Dietzia maris, (aka Rhodococcus maris), is a Gram-positive, non-spore-forming, aerobic, coccus bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 73%. Dietzia maris is probably a rare gut coloniser. (Rainey1995b)



  • This organism has been recovered from carp gut, soil, clinical samples (articular fluid - CCUG) and human faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). Is a rare opportunistic pathogen. A possible gut commensal.
