困難梭狀桿菌（C. difficile）會產生具抗藥性的芽孢，這些芽孢對酒精具有高度抗性，因此酒精性乾洗手無法有效殺死此菌。接觸隔離（contact precautions）要求進入病室必須穿戴手套與隔離衣，且最關鍵的步驟是處理完病人後必須使用肥皂與流動水洗手，以機械方式將芽孢從皮膚移除。此為感染控制中預防交叉傳播的核心原則。
Clostridium difficile produces resistant spores that are highly tolerant of alcohol, so alcohol-based hand rubs cannot effectively kill the organism. Contact precautions require gloves and a gown when entering the room, and most importantly, washing hands with soap and running water after caring for the client to mechanically remove spores from the skin. This is a core principle of infection control to prevent cross-transmission.
