About 20 brave Cantabrians have volunteered to be infected with hookworm parasites in an effort to find a cure for coeliac disease.
An Australian pilot study discovered people with severe gluten allergies who were also infected with hookworms did not have reactions when they ate gluten.
A group of Christchurch researchers have just received a $20,000 from the Lottery Grants Board to start a similar trial.
They hope to find out exactly how the hookworms prevent the allergic reactions, so they can turn that substance into a pill.
Otago University gastroenterology professor Richard Gearry said extreme cases of coeliac disease could have a major affect on people's quality of life, and he was hopeful the trial could help find a cure.
