Overview

  • Enterovibrio nigricans is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, coccobacillus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 47.9%. Enterovibrio nigricans is likely to be transient and not a long-term gut coloniser. (Pascual2009)



  • This organism has been recovered from fish kidney, Spain. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
