英伦广角 手工皂中的原料能提高细菌的抗性

 

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]

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.

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.

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.
