Adult worm measures 2-2.5 mm in length, lives in crypt's of Lieberkuhn in the duodenum and jejunum and lays eggs which hatch into larvae immediately.

It can cause chronic diarrhoea and hyperinfection in immunosupppressed perrson e,g person getting steroid or cytotoxic drug or in terminal pregnancy.During superinfection it can be found in urine also.
