Overview

  • Acinetobacter variabilis 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. Acinetobacter variabilis is likely to be transient and not a long-term gut coloniser. (Krizova2015)



  • This organism has been recovered from human faeces (CCUG) and clinical sources (blood, urine - CCUG). Can cause opportunistic infections, particularly in immunocompromised people. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe; unlikely to be a gut coloniser.
