Intervention/Comparison and Method Monoclonal antibodies: intravenous infusion of fully human monoclonal antibodies against C. difficile toxins A (CDA1) and B (CDB1) x 1 (n=101) Placebo (0.9% sodium chloride) x 1 (n=99) Recurrence of C. difficile infection, was defined as a new episode of diarrhea associated with a new positive stool toxin test after the resolution of the initial Clostridium difficile infection diarrheal episode and after discontinuation of metronidazole or vancomycin. Diarrhea was defined as three or more unformed stools per day for at least 2 consecutive days or more than six unformed stools in 1 day
