The antimicrobial triclosan is a common ingredient in hand soap.
手工香皂中有一种常见成分:抗菌性三氯生!L-RIk)MO%Jtfq
But it's also found in shampoos, deodorants, toothpaste, even lip gloss.
但在香波、除臭剂、牙膏,甚至润唇膏中也有这种物质JYsqEOae3HyJl!
So it's not too surprising that triclosan also shows up in blood, urine, breast milk and mucus.
因此也就不奇怪为什么在血液、尿液、乳汁以及其它分泌液中会检测出三氯生了lP%H!~b.=wmc@4v]!xM
But here's the weird thing—those triclosan residues may actually boost bacterial growth in our bodies.
但是更奇怪的事情其实是—这些三氯生残基也许能促进体内细菌的生长duY^)M6RGD8[2L|d
So says a study in the journal mBio.
这是根据在《微型生物》杂志上发表的一项研究报得出的结论9F7lZyTPEKPlu7
Researchers swabbed inside the noses of 90 adults.
研究人员们提取了90名成年人鼻腔中的物质样本Kdfna)jZWZ

37 of the 90 tested positive for triclosan—and those who did were twice as likely to have the bug Staphylococcus aureus living in their noses.
其中有37份对三氯生检测呈阳性—这些阳性样本中本人鼻腔中的金黄色葡萄球菌也是其他人中的两倍*4gRB9)nYqy
Rats, too, were more susceptible to staph if fed triclosan.
如果喂食含有三氯生的饲料给老鼠,它们也呈现出更容易被金黄色葡萄球菌感染的情况Ymr7!om|^*
Seems counterintuitive, but when bacteria are exposed to sublethal levels of antibiotics, they get stressed, and “they attach to surfaces and hunker down, in things we call biofilms."
看上去违反常理,但当细菌暴露在含有抗生素但是又不致死的环境中,它们受到这种胁迫,接触到其表面然后沉降,形成一种我们称之为生物膜体的物质f3R.&I!sy#Fh
That's study author Blaise Boles, of the University of Michigan.
这就是密歇根大学的布莱斯·波尔斯的研究内容wfKoZ3-SV&Fw0!WP[hec
He says that stash of staph could put your health at risk.
他表示金黄色葡萄球菌的囤积会危害到你的健康J+p|m^yp1aV
"Individuals that have Staph.aureus in their nose before they undergo surgery are about seven times more likely to get a Staph. aureus surgical site infection."
“手术前发现鼻腔中含有该菌的个体在外科手术的创伤感染上该菌的可能性要高7倍#+IBVPT,qg。”
Which is when you'll really need those antibiotics.
要是这种情况你就真的需要抗生素帮助了.,9cn![Q6ss!
