C-difficile is the major cause of antibiotic-associated diarrhea (AAD) and pseudomembranous colitis. This type of bacteria is established in the digestive tract and can induce severe diarrhea, nausea, fever, and stomach pain. Individuals who are at increased risk are those who require prolonged use of antibiotics and older persons. Toxin B causes the cells to be more enterable and can lead to hemorrhaging.
