Overview

  • Lacrimispora amygdalina, (aka Clostridium amygdalinum), is a Gram-positive, spore-forming, anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 32%. Lacrimispora amygdalina is probably a rare gut coloniser. (Rainey2011gBergey; Parshina2003)



  • This organism has been recovered from anaerobic digestive sludge. HuCA19 - a closely related bacterium (S16 94%) - was detected in 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.
