Correct answer: EArrange microbiota-based therapy after a completed anti-CDI antibiotic course

After multiple recurrences, microbiota-based therapy is an evidence-based recurrence-prevention option after standard antibiotic treatment. Antimotility monotherapy, chronic metronidazole and rifampin monotherapy are not appropriate, while colectomy is reserved for fulminant disease or complications.
