Overview

  • Gordonia terrae, (aka Rhodococcus terrae), is a Gram-positive, non-spore-forming, aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 64-69%. Gordonia terrae is probably a rare gut coloniser. (Tsukamura1971; Goodfellow1977)



  • This organism has been recovered from clinical sources (eye, blood, plural effusion - CCUG) and human faeces. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. A possible gut commensal.
