Changes in the susceptibility of Clostridium difficile strains to nitroheterocyclic drugs during serial passage for 20 days. Values represent the mean of three independent experiments, with error bars showing the standard error of the mean. MTZ, metronidazole; OND, ornidazole; NTZ, nitazoxanide; NFT, nitrofurantoin; NFZ, nitrofurazone; NIF, nifuroxazide; FZD, furazolidone; RFX, rifaximin. Mean starting minimum inhibitory concentrations (MICs) against CD196, BAA-1875 and R20291 were 0.01, 0.005 and 0.03 µg/mL, respectively.
