Individuals with certain types of bacteria in their gut may be more likely to respond well to cancer immunotherapy, researchers at the Harold C. Simmons Comprehensive Cancer Center found in a study of patients with metastatic melanoma. These bacteria somehow prime your immune system so that it’s better able to attack cancer cells and kill them. patients who responded well to the immunotherapy had three specific bacteria, Bacteroides thetaiotaomicron, Faecalibacterium prausnitzii, Holdemania filiformis. All three are common normal flora in the human intestinal tract.
