A bacterial infection is not just an unpleasant experience — it can also be a major health problem. Some bacteria develop resistance to otherwise effective treatment with antibiotics. Therefore, researchers are trying to develop new types of antibiotics that can fight the bacteria, and at the same time trying to make the current treatment with antibiotics more effective.

Researchers are now getting closer to this goal with a type of bacteria called Pseudomonas aeruginosa, which is notorious for infecting patients with the lung disease cystic fibrosis. In a new study, researchers found that the bacteria send out warning signals to their conspecifics when attacked by antibiotics or the viruses called bacteriophages which kill bacteria.
