Michael Mosley infests himself with tapeworms
The moment Michael Mosley discovered a tapeworm living inside him
BBC TV presenter Dr Michael Mosley has infected himself with a number of parasites in an effort to understand how they affect the human body.
He swallowed tapeworm cysts, stuck a leech on his arm, and tried to infest himself with lice, in a new BBC Four documentary programme.
The worms lived in his body for several weeks – and he felt no ill effects.
The stool samples he gave while infected will be used by scientists studying signs of parasitic infection.
