偽膜性腸炎（C. diff）是由產芽孢的細菌引起，其芽孢對酒精具有極強的抵抗力，一般的酒精乾洗手液（Alcohol-based hand rub）無法殺滅或移除芽孢。因此，物理性的手部清潔（Soap and water）透過流水沖洗與肥皂摩擦，是唯一能有效將芽孢從皮膚移除並預防院內交叉感染的標準措施。
Clostridioides difficile forms resilient spores that are resistant to alcohol-based hand sanitizers. Therefore, washing hands with soap and water is the most effective intervention, as the physical friction and rinsing are required to mechanically remove the spores from the skin.
