（单词翻译）

 This is Scientific American's 60-Second Science. I'm Karen Hopkin. This will just take a minute.

 
They say all roads lead to Rome. Unfortunately that ain't all that roads lead to. A new study shows that roads can promote the spread of antibiotic1-resistant2 bacteria. The findings appear in the Journal of the Royal Society Interface3. 
 
If you've ever taken antibiotics4 to get rid of an infection, you know it's important to complete the course of treatment—to limit the possibility that a resistant strain will arise. But that's just you, personally. How can we contain the spread of drug-resistant superbugs throughout the population? One way is to restrict bacterial5 traffic. 
 
Scientists studied the emergence6 of antibiotic resistance in an isolated7 area of northern Ecuador. And they found that five years after a new road was constructed, the villages closest to that road saw a rise in resistance to ampicillin and sulphamethoxazole—nearly double that found in more remote regions. Seems the motorway8 makes it easier for resistant microbes to migrate from person to person, and to immigrate9 in from out-of-town. 
 
So to stay safe on the highway, remember: wear your seatbelt. And wash your hands.
 
Thanks for the minute. For Scientific American's 60-Second Science, I'm Karen Hopkin.
