Mechanisms of Colonization Resistance Against Clostridioides difficile

J Infect Dis. 2021 Jun 16;223(12 Suppl 2):S194-S200. doi: 10.1093/infdis/jiaa408.

Abstract

Clostridioides difficile is an urgent antimicrobial-resistant bacterium, causing mild to moderate and sometimes life-threatening disease. Commensal gut microbes are critical for providing colonization resistance against C difficile and can be leveraged as non-antibiotic alternative therapeutics for the prevention and treatment of C difficile infection.

Keywords: Clostridioides difficile; bacteria; bile acids; microbiota; short-chain fatty acids.
