Overview

  • Mannheimia granulomatis, (aka Pasteurella granulomatis), is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, coccobacillus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 39.2%. Mannheimia granulomatis is probably a rare gut coloniser. (Angen1999; Ribeiro1989)



  • This organism has been recovered from diseased cattle. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: animal pathogen). It is an opportunistic pathogen. A possible gut commensal.
