What is a significant characteristic of the pathogenic amoeba Entamoeba histolytica?

Entamoeba histolytica is a pathogen known for causing amoebic dysentery, characterized by severe diarrhea that can include blood and mucus. This pathogenic amoeba can invade the intestinal lining, leading to ulceration and inflammation. Symptoms may range from mild diarrhea to severe dysentery, which can be life-threatening if not treated.

In addition to causing gastrointestinal issues, Entamoeba histolytica can also invade other organs, such as the liver, leading to the formation of liver abscesses, but this is typically a secondary manifestation rather than its primary characteristic. While it does possess a complex life cycle, this feature is not as significant in the context of its pathogenic effects as its ability to cause amoebic dysentery. The distinction of being pathogenic rather than non-pathogenic is central to understanding the impact of this organism on human health.
