copper can inhibit any given enzyme that "stands in its way," and stop the cell from transporting or digesting nutrients, from repairing its damaged membrane, from breathing or multiplying.

也有人认为，这就是为什么如此广泛的微生物容易受到铜的接触作用的原因。

It is also thought that this is why such a wide range of microorganisms are susceptible to contact action by copper.

实验结论：

*实验室测试表明，如果定期清洁，抗菌铜表面会在接触2小时内杀死99.9%以上的以下细菌：MRSA、VRE、金黄色葡萄球菌、产气肠杆菌、铜绿假单胞菌和大肠杆菌O157:H7。抗菌铜表面是标准感染控制实践的补充而非替代，已被证明可以减少微生物污染，但不一定能防止交叉污染或感染；用户必须继续遵循所有当前的感染控制实践。

*Laboratory testing shows that, when cleaned regularly, antimicrobial copper surfaces kill greater than 99.9% of the following bacteria within 2 hours of exposure: MRSA, VRE, Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, and E. coli O157:H7. Antimicrobial copper surfaces are a supplement to and not a substitute for standard infection control practices and have been shown to reduce microbial contamination, but do not necessarily prevent cross contamination or infections; users must continue to follow all current infection control practices.
