New antibiotics would silence bugs, not kill them

n future, the most effective **antibiotics might be those that don't kill any bacteria**. Instead the drugs will simply prevent the bacteria from talking with one another. Drug-resistant bugs are winning the war against standard antibiotics as they evolve resistance to even the most lethal drugs. It happens because a dose of antibiotics strongly selects for resistance by killing the most susceptible bacteria first. If, however, researchers can identify **antibiotics that neutralise dangerous bacteria without killing them**, the pressure to evolve resistance can be reduced. One way to do that is to target the constant stream of chatter that passes between bacteria as molecular signals.
