Overview

  • Sphingobacterium alimentarium is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 39.3%. Sphingobacterium alimentarium is likely to be transient and not a long-term gut coloniser. (Schmidt2012)



  • This organism has been recovered from human faeces and raw cow's milk. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
