Overview

  • Acinetobacter towneri is a Gram-negative, non-spore-forming, strictly aerobic, coccobacillus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. Acinetobacter towneri is likely to be transient and not a long-term gut coloniser. (Carr2003)



  • This organism has been recovered from activated sludge. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
