उत्तर
The disease called amoeba or amoebic dysentery is caused by a protozoan parasite called Entamoeba histolytica found in the large intestine of humans. The symptoms of this disease are constipation, abdominal pain and cramps, stools containing excessive mucus and blood clots, etc. The carriers of this disease are house flies, which carry the parasite from the stools of the infected person to food and food items, thereby contaminating them.
