Overview

  • Acinetobacter parvus is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, coccobacillus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 41.8%. Acinetobacter parvus is likely to be transient and not a long-term gut coloniser.



  • This organism has been recovered from clinical specimens (eye, ear, skin). The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Can cause opportunistic infections, particularly in immunocompromised people. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe suggests it is unlikely to be a gut coloniser.
