Comment: Infection with Entamoeba histolytica is found worldwide, but is much more common in tropical regions. Humans are the primary reservoir and infection occurs by ingestion of cysts from contaminated food or water. Infraction with E. histolytica can result in three different presentations. Patients maybe asymptomatic, they may have symptomatic invasive intestinal disease, or they may have extra intestinal disease (e.g. liver abscess). A positive serologic test is more likely to occur in patients with invasive amebiosis than in asymptomatic individuals
