科学美国人60秒 SSS Hand Soap Ingredient Can Up Body Bacteria Burden

（单词翻译）

The antimicrobial triclosan is a common ingredient in hand soap. But it's also found in shampoos, deodorants¹, toothpaste, even lip gloss². So it's not too surprising that triclosan also shows up in blood, urine, breast milk and mucus. But here's the weird³ thing—those triclosan residues⁴ may actually boost bacterial⁵ growth in our bodies. So says a study in the journal mBio. [Adnan K. Syed et al, Triclosan Promotes Staphylococcus aureus Nasal Colonization] 

抗菌三氯生是手肥皂中的常见成分。但它也发现在洗发精、 除臭剂、 牙膏、 甚至唇彩。所以它不是太令人吃惊的是，三氯生也显示在血液、 尿液、 乳汁和粘液。但这里是奇怪的事情 — — 那些三氯残留物可能实际上会促进细菌的生长，在我们的身体。所以说，期刊的一项研究。三氯生促进金黄色葡萄球菌鼻殖民化，[阿德南 K.赛义德 et al]

Researchers swabbed inside the noses of 90 adults. 37 of the 90 tested positive for triclosan—and those who did were twice as likely to have the bug⁶ Staphylococcus aureus living in their noses. Rats, too, were more susceptible⁷ to staph if fed triclosan. 

研究人员 90 成人的鼻子里面擦洗。90 37 呈阳性反应的三氯生 — — 和那些没有，两倍的有金黄色葡萄球菌 bug 生活在他们的鼻子。大鼠，也更容易受到金黄色葡萄球菌如果美联储三氯生。

Seems counterintuitive, but when bacteria are exposed to sublethal levels of antibiotics⁸, they get stressed, and “they attach to surfaces and hunker down, in things we call biofilms." That's study author Blaise Boles, of the University of Michigan. 

似乎有悖常理，但当细菌暴露到亚致死剂量抗生素，他们得到强调，"他们将附加到表面和蹲下，在东西我们叫生物膜。这是研究报告的作者布莱斯树干，密歇根大学。

He says that stash⁹ of staph could put your health at risk. "Individuals that have Staph. aureus in their nose before they undergo surgery are about seven times more likely to get a Staph. aureus surgical¹⁰ site infection." Which is when you'll really need those antibiotics. 

他说，藏匿的金黄色葡萄球菌能将你的健康处于危险之中。"有金黄色葡萄球菌的个人。在他们的鼻子之前他们接受手术治疗, 金黄色葡萄球菌是大约七倍更有可能得到金黄色葡萄球菌。金黄色葡萄球菌手术部位感染"。这是当你真的需要这些抗生素。
