Overview


  • Bhargavaea beijingensis, (aka Bacillus beijingensis), is a Gram-positive, non-spore-forming, strictly aerobic, non-motile, coccobacillus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 53.1%. Bhargavaea beijingensis is probably a rare gut coloniser. (Verma2012; Qiu2009)



  • This organism has been recovered from human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal.
