>Ameobiasis is an intestinal parasitic infection that is caused by Entameoba histolytica. The infection is spread through food and water or feca-oral route (meaning unclean hands after washing and then you ate or touched food that someone ate). Basically you get it anywhere which a contaminated water touches like fruits, vegetables that you wash with it. Chlorine and boiling cannot kill the parasite in a contaminated water. But Iodine-releasing tablet can.


Diarrhea with blood and mucus

Abdominal cramps

Dehydration – nausea, malaise, vomiting

If the infection spreads through the liver it can cause liver abscess. Sometimes the infection can also go asymptomatic (no symptoms) and when this happens the person is called a carrier. He can excrete the parasite and infect others.


First to treat is the dehydration if it is severe. Electrolyte and fluid losses should be corrected and replaced. Antibiotic such as Metronidazole (Flagyl) are given for a week. And Buscopan for the Abdominal cramps. If feverish, the person can take paracetamol as well.


For a week, less fiber intake is advisable. Coffee and tea are not allowed as well.

How is Ameobiasis diagnosed?

The Physician will require a fecalysis from you. Fecalysis result will show presence of E.histolytica cyst or trophozoite or both. RBC and Pus will also be present on the stool.
