Overview

  • Streptobacillus hongkongensis is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 24-26%. Streptobacillus hongkongensis is probably a rare gut coloniser. (Woo2014)



  • This organism has been recovered from clinical sources (pus). It is an opportunistic pathogen. A possible gut commensal.
