: a rod-shaped, spore-producing, gram-positive bacterial clostridium (Clostridium difficile) that occurs widely in soil and water and sometimes in human and animal intestines and that may produce a toxin causing intestinal illness (such as diarrhea) especially in those receiving antibiotic therapy Many healthy people harbor a few C. diff among the millions of bacteria in the colon.
