Description

From the face mites on our eyelashes to the amoebae that reproduce in our mouths, we all act as hosts to parasites—and we barely give them a second thought. In this program, Michael Mosley infects himself with some of the most powerful and surprising of these organisms to find out how this fascinating relationship works, from the disgusting tapeworm to head lice and leeches. He is carefully monitored over a period of weeks as his parasites get used to their new home, revealing how an infestation takes hold and the effect it has on the human body. He also explores the growing scientific evidence that suggests some parasites might even be beneficial. Over the weeks, Michael itches and scratches his way to a new-found respect for these fascinating organisms.
