Now, listen to Part One of the interview.
W: I’m Kelly Klein and today I’m speaking with David Grimm, online news editor for Science, about some of the recent stories from our online daily news site.(1-1)So Dave, you are going to talk with me about "how not to treat a disease" , are you?
M: Right, Kelly. Well,(1-2)this study is a little bit counter-intuitive because it suggests that taking two drugs at once may actually be worse for treating the disease than better. This approach, especially taking two antibiotics at once, is called synergistic therapy.(2)And what researchers thought the advantage was that, you know, different drugs attack different parts of an invading microorganism, like a bacterium.
W: Just as we have heard that doctors use these drug combinations in everything from treating HIV to MRSA, which is a very highly resistant pathogen that’s often acquired in hospitals.
M:(3)But this new study suggests that maybe two drugs at once isn’t such a good idea.
W: Right, because as soon as we start talking about antibiotics we have to start thinking about bacterial resistance.
M: Exactly, and that seems to be what happens here.(4)What happens when bacteria evolve resistance is that they find some way to overcome, or members of their population find a way to overcome the drug, and when the drug kills all the other bacteria off, you’ve got these few bacteria that are left that are resistant, and they are able to multiply. And all of a sudden your drug doesn’t work anymore.
W: That explains the appearance of resistance.’ Then, what will happen if we use two antibiotics together?
M: Well, it turns out that seems to be happening even more dramatically when you use two antibiotics at once, or at least that’s what these researchers have shown. What they did was they took E. coli, which can be a pretty nasty pathogen, and they treated it with two common antibiotics: doxycycline and erythromycin.(5)They basically put these E. coli in a test tube. They added both drugs, and after a day, the drugs seemed to almost completely wipe out the E. coli, which is sort of expected.
W: It doesn’t sound too bad, so far.
This is the end of Part One of the interview.

5. What happened the day after researchers put two antibiotics in the test tube containing E. coli?
