Overview


  • Yonghaparkia alkaliphila is a Gram-positive, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 71.1-71.6%. Yonghaparkia alkaliphila is unlikely to be a gut coloniser. (Yoon2006a)



  • This organism has been recovered from human faeces, and alkaline soil. 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.

  • QUIRKS
  • Obligate aerobe, no spore formation and doesn't grow at 38C, so probably a gut non-coloniser.
