Presenter sees his own tapeworm

TV presenter Michael Mosley has infected himself with a series of parasites in an effort to understand how they affect the human body.

Here, he sees a tapeworm that is living inside him for the first time, via a tiny camera that he swallowed like a pill.

'Michael Mosley: Infested! Living with parasites' will be broadcast in BBC Four's natural history season, starting in February.
