難辨梭狀芽孢桿菌（C. diff）會產生具有高度抗藥性的孢子（Spores）。酒精性乾洗手（Alcohol-based hand rub）無法殺滅孢子，僅能透過機械性摩擦將其去除。臨床實證顯示，照護 C. diff 病人後，必須使用肥皂（Soap）與流動清水（Water）進行徹底洗手，利用沖洗的機械力量將孢子完全移除，這是預防院內感染擴散的標準程序。
Soap and water is the most appropriate hand hygiene method for clients with Clostridioides difficile because mechanical friction and rinsing are required to physically remove spores. Alcohol-based sanitizers and antiseptic scrubs are ineffective against C. diff spores, making standard handwashing essential to prevent nosocomial transmission.
