All 238 Clostridium difficile isolates were susceptible to metronidazole and vancomycin, whereas 84% and 1% were resistant to clindamycin and fusidic acid. Etest MICs for metronidazole were lower than agar dilution MICs (P < 0.01) but without difference in susceptible-intermediate-resistant categorization. No particular PCR ribotype was associated with clindamycin or fusidic acid resistance.
所有238株艰难梭菌分离株对甲硝唑和万古霉素敏感,而对克林霉素和夫西地酸的耐药率分别为84%和1%。甲硝唑的Etest最低抑菌浓度低于琼脂稀释法最低抑菌浓度(P < 0.01),但在敏感-中介-耐药分类方面无差异。没有特定的PCR核糖型与克林霉素或夫西地酸耐药相关。
