The bactericidal activity of isopropanol was determined against Enterococcus faecium ATCC 6057, ST 796 (isopropanol-tolerant strain) and Enterococcus hirae ATCC 10541 (EN 13727). Isopropanol at 60% and 70% were effective (≥5.38 log-reduction) in 15 s against all strains but 23% isopropanol was not (<0.99 log-reduction in ≤15 min). Isopropanol at 70% was tested against E. faecium in the four-field test. Eight millilitres was not effective enough in 1 min (<5 log-reduction), whilst 16 mL was effective (≥5.85 log-reduction). Healthcare workers can be reassured that 60% and 70% isopropanol with an appropriate volume are effective against E. faecium.
异丙醇对粪肠球菌 ATCC 6057、ST796（耐异丙醇株）和屎肠球菌 ATCC 10541（EN13727）的杀菌活性进行了测定。60%和 70%的异丙醇在 15 秒内对所有菌株均有效（≥5.38 对数减少），但 23%的异丙醇无效（≤15 分钟内<0.99 对数减少）。70%的异丙醇在四象限测试中针对粪肠球菌进行了测试。1 分钟内 8 毫升的效果不够（<5 对数减少），而 16 毫升则有效（≥5.85 对数减少）。医护人员可以放心，60%和 70%的异丙醇用适当的量对粪肠球菌是有效的。
