The Great British Germ Hunt

Kate Quilton explores the invisible world of bacteria all around us, discovering the germs that live on us and in us and finding out why they're crucial for our health. In a scientific first, volunteers at a music festival are tested to see whether a weekend of partying improves their bacterial diversity. A nationwide germ swabathon reveals the incredible bacterial species living on everything from supermarket trolleys to door handles all across the country. And two ordinary British homes are put under the microscope to reveal the good, the bad and the ugly germs that we live with.
