A medical dressing that changes colour when it detects infection could cut the unnecessary use of antibiotics, say scientists at Bath University.

It works by releasing fluorescent dye from tiny capsules when toxins are given out by bacteria in a wound.

This allows doctors to identify bacterial infections and treat them more quickly, particularly in children with burns.

Researchers said it could help to save lives.

Children with burn wounds are particularly susceptible to bacterial infections because of their immature immune systems.

These infections can slow the healing of wounds, leading to longer stays in hospital and sometimes permanent scarring. In severe cases, infections can kill.

That will save a lot of anti-b's being given out.
