Endo-parasites and helpful organisms
People with MS are taking part in a new research trial by being infected with hookworms.
Researchers at Nottingham's Queen Medical Centre are looking at how the worms can affect the immune system of people living with the illness.
Jo Hallam, from Mansfield who is taking part in the trial, said: "I'm not thinking this is going to find a cure but I'm hoping it will lead to something that will alleviate the symptoms.
"Even if this identifies something that can help people with MS it is definitely worthwhile."
