Repeated Dientamoeba fragilis infections: a case report of two families from Sydney, Australia

Abstract

We report cases of two unrelated families who both presented with recurrent Dienta-moeba fragilis infections. Subsequent antimi-crobial therapy resulted in the clearance of D. fragilis and total resolution of gastrointestinal symptoms in both families. This report high-lights the potentially recurrent nature of D. fragilis infections and the need for laboratories to routinely test for this organism.
