Biology GCSE: Infested by tapeworms
In this short film Dr Michael Mosley visits Kenya to see how the beef tapeworm needs to infect both beef cattle and humans to complete its life-cycle.
He collects some infected beef in Kenya, finds the tapeworm cysts and infects himself.
Footage of the cysts inside him is seen, followed ten weeks later by footage of the one metre long adult worms.
Michael Mosley describes the fact that he cannot feel it inside him despite its length.
This short film is from the BBC series, Michael Mosley: Infested! Living with parasites.

Tapeworms could be investigated to familiarise or reinforce the concepts of parasite, host and secondary host.
The relationship could be looked at in terms of benefits and harm related to energy and nutrition.
This short film is suitable for teaching biology at KS4/GCSE in England, Wales and Northern Ireland and National 4/5 in Scotland.
