Overview

  • Microvirga aerophila is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 62.2%. Microvirga aerophila is likely to be transient and not a long-term gut coloniser. (Weon2010)



  • This organism has been recovered from human faeces and air sample from Korea. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe; unlikely to be a gut coloniser.
