A type of blue clay found only in the ground in the US state of Oregon could be used to fight antibiotic resistant bacteria.

Scientists say the unusual soil can kill bacteria which are difficult to destroy using drugs, and could help fight infections in humans.

Diarrhoea bug E.coli and hospital superbug MRSA could both be in the firing line as scientists managed to kill them with the clay in a lab.

Clay is already commonly used in skin treatments like face masks, and for their study the scientists mixed it with liquid to test its antibacterial properties.

The researchers say their findings are an ‘important advance’ in exploring new ways to fight infections as increasing numbers become resistant to medicine.

Experts from Arizona State University and the Mayo Clinic say Oregon blue clay could help medics to fight disease-causing bacteria in wounds.

In lab studies they found applying the clay to samples of infectious bacteria killed them off.

These included E.coli, Staphylococcus infections and MRSA, which is immune to most common antibiotics including penicillin and amoxicillin.
