Under what circumstances would you recommend early fecal microbiota transplantation over antibiotic treatment or bezlotoxumab in a patient with recurrent C. difficile infection?

Assuming donor stool is available, if the patient is not expected to need another course of antibiotics in the foreseeable future, I would recommend FMT.

Rarely. Bezlo not available. For someone with MDROs might be useful, and depends on availability.
