Coprococcus is a genus of obligately anaerobic, nonmotile, Gram-positive cocci that are part of the human and animal gut microbiota. ^[2]

Coprococcus spp. are notable for their ability to ferment dietary fibers into short-chain fatty acids, especially butyrate, which is a key metabolite that supports colonocyte health, enhances mucosal integrity, and has anti-inflammatory properties. The genus is considered an important contributor to colonic homeostasis and overall gut health. ^[3]

Depletion of Coprococcus has been reported in patients with colorectal cancer, although a direct protective role remains to be fully established. ^[4]

One species, Coprococcus comes, may also influence the efficacy of blood pressure-lowering medications by modifying gut metabolism of esterified angiotensin-converting enzyme (ACE) inhibitors. ^[5]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) ^[1] and the National Center for Biotechnology Information (NCBI) ^[6]
