Biology GCSE: Michael Mosley - Infested! Living with parasites

Dr Michael Mosley explores the bizarre and fascinating world of parasites by turning his body into a living laboratory and deliberately infesting himself with them.

By the end of his infestation, Michael learns a new-found respect for these extraordinary creatures, which can live off and even take control of their hosts for their own survival.

These short films are from the BBC Two series, Michael Mosley: Infested! Living with parasites.
