The effect of alcohol hand rub was tested in eradicating Escherichia coli, and compared with hand wash using ozonized tap water or soap and water. Alcohol eradicated all bacteria in 10 out of 35 participants, but with an average (SD) of 2330 (4227) cfu/mL left after disinfection, whereas ozonized water removed all bacteria in 10 out of 55 participants, with an average of only 538 (801) cfu/mL left (P = 0.045). Soap washing was the most effective with total removal of bacteria in six out of 20 participants, with an average of 98 (139) cfu/mL (P = 0.048 and 0.018 versus ozonized water and alcohol, respectively).
酒精手部消毒剂的除菌效果在 35 名参与者中的 10 人中得到了测试，并与使用臭氧水或肥皂和水的手部清洗进行了比较。酒精在 10 名参与者中的 35 名参与者中消灭了所有细菌，但消毒后平均（SD）仍有 2330（4227）cfu/mL 残留，而臭氧水在 10 名参与者中的 55 名参与者中消灭了所有细菌，平均只有 538（801）cfu/mL 残留（P=0.045）。肥皂洗涤是最有效的，在 20 名参与者中的 6 名中完全去除了细菌，平均为 98（139）cfu/mL（P=0.048 和 0.018 分别与臭氧水和酒精相比）。
