An amoeba is a single-celled organism that can change shape by extending and retracting pseudopods. Amoebas live in freshwater, saltwater, moist soil, and the moist parts of animals. They ingest bacteria, other microbes, and plant cells through endocytosis. Amebiasis is a disease caused by the parasitic amoeba Entamoeba histolytica, which can infect the intestines and other organs. Symptoms include diarrhea, fatigue, and nausea. Amebiasis is diagnosed through stool testing and other medical exams. It can be prevented by avoiding contaminated food and water and maintaining good hygiene. Amoebas also benefit ecosystems by recycling nutrients in

11. Diagnosed
Your medical and travel history and
testing stool samples for the presence of E.
histolytica cysts ; other tests may also be
included such as liver infection tests.

12. PREVENTION
• It is possible to prevent amebiasis by
avoiding contaminated food and/or
water, good sanitation techniques,
and avoidance of contaminated
food handlers and other carriers of
the parasite. There is
a vaccine available for animals, and
for human we use antibiotics
(metronidazole, dehydroemetine or
chloroquine).
