Entamoeba dispar : A Rare Case of Enteritis in a Patient Living in a Nonendemic Area

Abstract

Entamoeba dispar , a common noninvasive parasite, is indistinguishable in its cysts and trophozoite forms from Entamoeba histolytica , the cause of invasive amebiasis, by microscopy. To differentiate the two species seems to be a problem for laboratory diagnosis. Recent experimental studies showed that E. dispar can be considered pathogenic too. We present a rare case of enteritis due to E. dispar .
