Overview

  • Actinobacillus ureae, (aka Pasteurella ureae), is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 41.2-43.7%. Actinobacillus ureae is unlikely to be a gut coloniser. (Olsen2005Bergey)



  • This organism has been recovered from the human nose. Can cause ozaena and other infections. 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.
