Resumen

Amebiasis is a parasitic infection caused by the protozoan parasite Entamoeba histolytica. Most cases of amebiasis occur in developing countries, where access to clean water and proper sanitation is limited. However, the condition can also be seen in developed countries among travelers who have visited areas where amebiasis is endemic. Symptoms of amebiasis can include diarrhea, abdominal pain, fever, and rectal bleeding. If left untreated, the infection can progress to involve the liver (amebic hepatitis) or the brain (amebic meningoencephalitis).
