Abstract
Entamoeba infection is a major cause of dysentery in developing countries. Association between Entamoeba histolytica as a protozoa and occurrence of hemolytic uremic syndrome is growing. On the other hand, metronidazole is also deemed as a cause of hemolytic uremic syndrome. This may make the clinicians suspicious about the real pathogenesis of hemolytic uremic syndrome. In this case report a 9 year old girl presented to emergency department with acute renal failure following an amebiasis dysentery and 5 days of metronidazole usage. With diagnosis of hemolytic uremic syndrome, the patient was put under appropriate treatment protocol.
