 Entamoeba polecki
What is Entamoeba polecki?Entamoeba polecki (ENT-a-ME-ba po-leh-key) is a single-celled intestinal parasite. It is best known as a parasite of pigs and monkeys. It sometimes is found in the intestines or stool of other animals and people.
In what parts of the world has Entamoeba polecki been found in people?Two of the most common areas have been in Papua New Guinea and Southeast Asia. Occasional cases in other parts of the world have been reported.
How do people get Entamoeba polecki?By swallowing the parasite. This could happen in various ways. But we don’t know which ways are the most common. For example, some people who have E. polecki had direct contact with animals, such as pigs, whereas other people did not. In general, we think people can get E. polecki by either:
How common is Entamoeba polecki in people?We don’t know. But we think it’s rare.
Where is Entamoeba polecki found in the human body?Only in the intestines (bowels). It does not spread to other parts of the body.
How is Entamoeba polecki detected in people?By looking at stool samples under a microscope. Sometimes it’s a good idea to have an expert confirm the diagnosis. Other types of parasites, cells, and even debris may be mistaken for E. polecki.
Can Entamoeba polecki cause intestinal (bowel) symptoms?We’re not sure. In most people, E. polecki probably is a harmless intestinal parasite. People who have E. polecki typically either feel fine — or — have some symptoms (such as loose stools or stomach cramps) that are caused by something else. But we don’t know enough about E. polecki (or about related parasites/strains) to exclude the possibility that its presence in the intestines might make some people feel sick. Even so, it’s always a good idea to make sure that other possible causes of the symptoms aren’t missed.
What should I do if I have Entamoeba polecki and no other cause for my intestinal symptoms has been found?You should discuss your situation with your health care provider. People who have E. polecki usually do not need treatment. However — depending on your circumstances — your health care provider might decide to prescribe medication, to see if your symptoms go away.
