Fidaxomicin (FDX) is approved to treat Clostridium difficile associated diarrhea, and is superior to vancomycin in providing a sustained clinical response (cure without recurrence in the subsequent 25 days). Mechanism(s) behind the low recurrence rate of FDX-treated patients could be multifactorial. Here, we tested effects of FDX, its metabolite OP-1118, and vancomycin on spore germination and determined that none affected the initiation of spore germination but all inhibited outgrowth of vegetative cells from germinated spores.
