Overview

  • Sphingobacterium faecium is a Gram-negative, non-spore-forming, aerobic, non-motile, rod-shaped bacterium. The DNA G+C content is 39.0-40.4%. Sphingobacterium faecium is probably a rare gut coloniser. (Takeuchi1992; Editorial2010bBergey)



  • This organism has been recovered from human faeces. 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. A possible gut commensal.

  • PM2-P1-29 contains the tet(X) gene encoding monooxygenase-degrading tetracycline, and it transforms tetracycline in vivo. The tet(X) gene is widely detected in the environment and commensal Bacteroides spp., where it is nonfunctional. In recent years, tet(X) has been reported in a duck pathogen and in diverse clinical isolates. The TetX enzyme can transform all known tetracyclines, including tigecycline; thus, the increasing prevalence of tet(X) is of great concern. PM2-P1-29 remains the only bacterium harboring tet(X) with demonstrated TetX activity in its native host. [PMID: 25301646]

    The genus Sphingobacterium are gram-stain-negative, aerobic, rod-shaped bacteria that are positive for catalase and oxidase, and contain menaqui- none-7 (MK-7) as the characteristic respiratory quinone. [PMID: 28699577] The strain was isolated from soil. PM2-P1-29 contains the tet(X) gene encoding monooxygenase-degrading tetracycline, and it transforms tetracycline in vivo.
