從倫敦公共場所採集的細菌中，約一半都對兩種以上常用抗生素（例如青黴素，紅黴素）具有耐藥性。
細菌耐藥性的驚人現狀
如果你有細菌恐懼症（是個潔癖），卻不得不呆在城市裡，那麼這幾條生存法則你必須遵守：觸摸廁所門把手之前先在手心墊一張紙巾；用鞋子提起馬桶座圈；在自動取款機、人行橫道紅綠燈和電梯上用指節或手背觸摸按鈕，決不用指尖。我很了解這些，因為我就有潔癖。
最近，一項新研究在某種程度上證明，我的行為是正當的。倫敦的研究人員在公共購物中心、火車站和醫院公共區域的各類表面進行了取樣，發現這些地方潛伏著大量的抗生素耐藥菌。
之後，科學家用拭子在全倫敦各處進行採集，最終得到 600 份葡萄球菌屬（Staphylococcus）細菌樣本。其中，約一半細菌對兩種以上的……[查看全文]
London Is Crawling with Drug-Resistant Microbes
If you’re a germaphobe navigating the city, there are certain mandatory rules of engagement: Use a paper towel to shield your hand as you touch the bathroom door handle. Lift toilet seat covers with your shoe. Touch buttons at ATMs, and crosswalks, and elevators with a knuckle or the back of your hand—never a fingertip. I know this, because I am that person.
And a new study in the journal Scientific Reports somewhat justifies my behavior. Because when researchers in London sampled all those kinds of surfaces—in public shopping centers, train stations and common areas in hospitals—they found a whole lot of antibiotic-resistant bacteria lurking there.
The scientists swabbed sites all over London and ended up with 600 samples of Staphylococcus bacteria. Of those, nearly half were resistant to two or more…[read more]
