Antibiotic resistance: Could a scratch prove deadly?

The world could soon be "cast back into the dark ages of medicine" unless action is taken to tackle the growing threat of resistance to antibiotics, Prime Minister David Cameron has said.

He has announced a review into why so few anti-microbial drugs have been introduced in recent years.

Speaking to BBC Breakfast, GP Dr Farrah Sheikh warned of the dangers posed if antibiotics do not work, and suggested that the time could come when a scratch might prove deadly.
