Overview
Ameoebic liver abscess is caused by a protozoan Entamoeba histolytica. It is the most common extraintestinal manifestation of amoebiasis.
Pathophysiology
- Amoebic liver abscess is the most common extraintestinal manifestation of amoebiasis.
- There are two genetically different species of entamoeba.[1] They are
- Mode of transmission of Entamoeba histolytica include
- Fecal-oral route (ingestion of food and water contaminated with feces containing cysts)
- Hepatocyte programmed cell death induced by Entamoeba histolytica causes amoebic liver abscess.
- The infection is transmitted to liver by portal venous system.[2]
- Clinical syndromes associated with Entamoeba histolytica infection
