It is a stomach bug known to afflict some backpackers with bouts of uncomfortable diarrhoea.
Now scientists say they have discovered how the parasites that cause giardiasis - one of the world's most common gastric diseases - make people ill.
Giardia parasites mimic human cell functions to break apart cells in the gut and feed inside, researchers found.
This also allows bacteria already present in the body to join in and feed from the same nutrients, they said.
