Money is one of the most frequently passed items in the world. The aim of this study was to ascertain the survival status of bacteria including Staphylococcus aureus, Escherichia coli, and Vancomycin- Resistant Enterococci (VRE) on banknotes from different countries and the transmission of bacteria to people who come in contact with the banknotes. The survival rate was highest for the Romanian Leu yielding all three microorganisms used after both three and six hours of drying. Furthermore, the Leu was the only banknote to yield VRE after one day of drying. Other currencies either enabled the survival of Extended-Spectrum Beta-Lactamases (ESBL) and VRE (e.g. Euro), but not of MRSA, or the other way round (e.g. US Dollar). While a variety of factors such as community hygiene levels, people's behaviour, and antimicrobial resistance rates at community level obviously have influence on the transmission of resistant microorganisms, the type of banknote-paper may be an additional variable to consider.
钞票是世界上流通最频繁的物品之一。本研究的目的是确定包括金黄色葡萄球菌、大肠杆菌和耐万古霉素肠球菌（VRE）在内的细菌在来自不同国家的钞票上的存活状态，以及这些细菌传播给接触钞票的人的情况。在干燥三小时和六小时后，罗马尼亚列伊上三种微生物的存活率最高。此外，列伊是唯一一种在干燥一天后仍能产生 VRE 的钞票。其他货币要么能够存活扩展谱β-内酰胺酶（ESBL）和 VRE（如欧元），但不能存活 MRSA，要么反之（如美元）。虽然钞票种类等多种因素，如社区卫生水平、人们的行为以及社区层面的抗生素耐药率，显然会影响耐药微生物的传播，但钞票用纸的类型可能是另一个需要考虑的变量。
