I find the possibility of invincible bacteria terrifying.

Scientists have found bacteria that can't be killed by colistin, our last-resort antibiotic. The scary thing is that the resistance can pass between bacteria species quickly. This genetic mutation has already been found in a range of bacteria, and could spread across the world.

For years we've known that overusing antibiotics causes drug resistance. When will we learn our lesson?

Medicine is at risk of going back to the Dark Ages. Without antibiotics, common bacterial infections could be deadly and surgery would be highly risky. We need to act.

antibiotic resistance

The drug resistance that's been discovered was probably caused by too much use of antibiotics in farm animals.
