What organ does entamoeba histolytica invade?

Entamoeba histolytica primarily invades the intestines, specifically the colon. It can cause amoebic dysentery by damaging the intestinal lining, leading to symptoms such as diarrhea, abdominal pain, and in severe cases, colonic ulcers. In some instances, the parasite can also spread to other organs, such as the liver, causing amoebic liver abscesses.
