Answer to Case 53

Answer: Iodamoeba butschlii
The key to identification of this ameba is the presence of the large dark nuclear karysome and the characteristic cytoplasmic vacuole.

Although this ameba is non-pathogenic in humans, its presence indicates that the patient has been exposed to fecally contaminated food or water. Therefore, a parasitic cause should not be exluded if it fits with the clinical presentation, and additional stool samples should be obtained for examination.
