What is entamoeba histolytica?

Entamoeba histolytica is a protozoan parasite that causes amoebic dysentery and other related gastrointestinal diseases. It is commonly found in regions where sanitation and hygiene are poor. This parasite can exist as both a cyst, which is how it enters the human digestive system, and an invasive trophozoite form that causes tissue damage in the colon. The symptoms of infection include diarrhea, fever, abdominal pain, rectal bleeding, and weight loss. In severe cases, it may lead to liver abscesses and can even prove fatal. It is essential to practice proper hygiene and safe water practices to prevent infection with this parasite. Treatment typically involves the use of antibacterial drugs.
