Overview

  • Lysinibacillus macroides, (aka Bacillus macroides), is a Gram-variable, spore-forming, strictly aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 38.2%. Lysinibacillus macroides is likely to be transient and not a long-term gut coloniser. (Pringsheim1947; Pringsheim1950; Coorevits2012)



  • This organism has been recovered from cow faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe; unlikely to be a gut coloniser.
