Overview

  • Pseudoxanthomonas spadix is a Gram-negative, non-spore-forming, aerobic, non-motile, rod-shaped - curved bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 68.5%. Pseudoxanthomonas spadix is probably a rare gut coloniser. (Young2007)



  • This organism has been recovered from an oil-contaminated site, Taiwan.. 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.
