Summary: Gastrointestinal disease is common in the Australian population and there are a wide variety of causes. The parasite Dientamoeba fragilis is emerging as a common cause of diarrhoea and abdominal pain, but until recently was neglected and not diagnosed. We will study the culture, antigens and excreted secreted products of this parasite, in order to develop a new diagnostic method using monoclonal antibodies for detection of this parasite in faeces. Correct diagnosis will allow treatment, thereby preventing disease amongst Australians. We will also develop an animal model which will allow study of treatment regimes and pathology associated with infection
