Overview

  • Pararheinheimera texasensis, (aka Rheinheimera texasensis), is a Gram-negative, non-spore-forming, 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 48.2%. Pararheinheimera texasensis is probably a rare gut coloniser. (Merchant2007)



  • This organism has been recovered from a freshwater lake, United States. 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.
