编辑先生：钱是最常流通的物品之一，当它被污染时，可能会在人与人之间的微生物传播中发挥作用。1虽然纸币被报道为多重耐药病原体的可能传播者，1但据我们所知，没有关于日元上耐药细菌的信息;因此，我们调查了1000日元纸币的污染情况。菌落数细菌1 1枯草芽孢杆菌2 3枯草芽孢杆菌3无生长4 1头葡萄球菌5无生长6无生长7无生长8 1表皮葡萄球菌9无生长10无生长11无生长12无生长13 1枯草芽孢杆菌14无生长15无生长16无生长17 1球形芽孢杆菌18无生长19无生长20无生长21无生长22 1藤黄微球菌23无生长24无生长25无生长26 7（1，5，1）克里斯汀微球菌，中生明串珠菌，藤黄微球菌27 1枯草芽孢杆菌28 1坚强芽孢杆菌29无生长30无生长31无生长32（1，21）枯草芽孢杆菌，11 Koucuria kristinae，坂崎肠杆菌35 2藤黄微球菌36无生长37 1生殖棒杆菌38 31胶质口腔球菌39 1枯草芽孢杆菌40 2鲁氏不动杆菌纸币在同时处理食物时可能对公众健康构成风险，并可能导致医院感染的传播。2研究表明，污染率从高价值到低价值的纸币增加，这表明低价值的纸币流通更多，因此污染的机会更大。3千日元纸币是日本银行目前发行的面值最低的纸币。虽然在不同研究中鉴定的分离细菌种类可能因所用方法、季节、环境条件、货币类型（硬币或钞票）或当地社区植物群而异，但一般而言，革兰氏阳性菌通常是最主要的。1，4细菌属和微球菌属的检出率高于葡萄球菌属，常引起皮肤感染性疾病。
Dear Editor, Money is one of the items most frequently passed from hand to hand; when contaminated, it may play a role in the transmission of microorganisms between people. 1 Although paper money has been reported as a possible transmitter of multidrug‐resistant pathogens, 1 to the best of our knowledge, no information regarding drug‐resistant bacteria on the Japanese Yen is available; therefore, we investigated the contamination of 1000 Yen notes. Number of colonies Bacteria 1 1 Bacillus subtilis 2 3 Bacillus subtilis 3 No growth 4 1 Staphylococcus capitis 5 No growth 6 No growth 7 No growth 8 1 Staphylococcus epidermidis 9 No growth 10 No growth 11 No growth 12 No growth 13 1 Bacillus subtilis 14 No growth 15 No growth 16 No growth 17 1 Bacillus sphaericus 18 No growth 19 No growth 20 No growth 21 No growth 22 1 Micrococcus luteus 23 No growth 24 No growth 25 No growth 26 7 (1, 5, 1) Micrococcus kristinae, Leuconostoc mesentoroides, Micrococcus luteus 27 1 Bacillus subtilis 28 1 Bacillus firmus 29 No growth 30 No growth 31 No growth 32 22 (1, 21) Bacillus subtilis, Rothia amarae 33 23 Bacillus subtilis 34 11 Koucuria kristinae, Enterobactor sakazaki 35 2 Micrococcus luteus 36 No growth 37 1 Corynebacterium genitalium 38 31 Stomatococcus mucilaginosus 39 1 Bacillus subtilis 40 2 Acinetobacter lwoffii Paper currency may pose a public health risk when associated with the simultaneous handling of food and may lead to the spread of nosocomial infections. 2 Studies have shown that the rate of contamination increases from higher‐value to lower‐value notes, suggesting that lower‐value notes circulate more and thus have a greater chance of contamination. 3 The 1000 Yen note is the banknote with the lowest value currently issued by the Bank of Japan. While the kind of isolated bacteria identified in different studies might vary owing to the methods used, season, environmental conditions, type of money (coin or banknote), or local community flora, in general, gram‐positive bacteria were generally the most predominant. 1, 4 There were more Bacillus and Micrococcus than Staphylococcus, which often caused the skin infectious disease.
