E. dispar, or Entamoeba dispar, is a type of single-celled organism known as an amoeba. It is primarily found in the intestines of humans and is closely related to Entamoeba histolytica, which can cause disease. However, E. dispar is generally considered non-pathogenic, meaning it usually does not cause illness in healthy individuals. This organism is transmitted through contaminated food and water, similar to other intestinal parasites. While most people infected with E. dispar remain asymptomatic, it can be detected through stool tests. Understanding E. dispar is important for differentiating it from its pathogenic relatives in medical diagnostics.
