Overview


  • Neisseria elongata is a Gram-negative, non-spore-forming, aerobic, non-motile, diplobacilli bacterium. It has been detected in at least 8 gut microbiome compilation studies or metastudies. The DNA G+C content is 53%. Neisseria elongata is probably a common, although minor, coloniser of the gut. (Barrett1994; Bovre1970; Dewhirst1993; Tonjum2005Bergey)



  • This organism has been recovered from human faeces, and clinical sources (appendix, nasopharynx, blood - CCUG). The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. It is an opportunistic pathogen. A possible gut commensal.
