It's hard to think of life without antibiotics. But that's exactly what scientists are starting to plan for as bacteria increasingly become resistant to drugs.

Predatory bacteria might be one alternative. They could be injected into the patient and eat the bacteria that cause disease.

Scientists have tested the idea on fish infected with a bug that causes a common type of food poisoning - 60% of the fish were cured and survived. It's an interesting first step, but lots more tests are needed before treatment can even be considered in humans.
