Overview

  • Desulfovibrio trichonymphae is a Gram-stain unknown, non-spore-forming, anaerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 54.8%. Desulfovibrio trichonymphae is unlikely to be a gut coloniser. (Sato2009; Kuwahara2017)



  • This organism has been recovered from termite gut. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Intracellular mutualist of Trichonympha agilis protist. Suited to H2/SO4 respiration, which prevents the buildup of H2 and subsequent inhibition of the fermentation process in the hindgut.
