Overview

  • Heyndrickxia oleronia, (aka Bacillus oleronius), is a Gram-negative, spore-forming, strictly aerobic, non-motile, short rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 35%. Heyndrickxia oleronia is likely to be transient and not a long-term gut coloniser. (Heyndrickx2012; Kuhnigk1995)



  • This organism has been recovered from the hindgut of termites, diary products and dairy equipment. 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. Likely to be transient and not a long-term gut commensal.
