The tale of antibiotics is a cautionary one, and economic incentives are often to blame.

In 1928 a young bacteriologist named Alexander Fleming failed to tidy up his petri dishes before going home to Scotland on holiday. On his return, he famously noticed that one dish had become mouldy in his absence, and the mould was killing the bacteria he'd used the dish to cultivate. It's hard to overstate the impact of antibiotics on medicine, farming and the way we live. But, as Tim Harford explains, the story of antibiotics is a cautionary one. And unhelpful economic incentives are in large part to blame. Producer: Ben Crighton Editors: Richard Knight and Richard Vadon.

Professor Monique van Hoek is one of the researchers involved in the experiment. (Photo: A group of Komodo dragons feast on a fresh goat carcass inside a zoo in Indonesia.
