Overview

Amoebiasis may be classified based on the responsible organism (E. histolytica vs. E. dispar) or based on the extent of invasion of the infection (luminal [asymptomatic] vs. invasive intestinal or extraintestinal [symptomatic]). E. histolytica may cause either luminal or extraluminal infection, whereas E. dispar can only causes luminal infection.

Classification

Classification Based on Responsible Organism

  • E. histolytica
Responsible for all symptomatic amoebiasis
May casuse either luminal (asymptomatic) or invasive infection (symptomatic)
  • E. dispar
Responsible for the majority of colonization cases
Only causes luminal infection (asymptomatic)

Classification Based on Invasion

  • Luminal amoebiasis: parasite localized to the intestines, patients are asymptomatic
  • Invasive amoebiasis: parasite was able to damage the integrity of the intestinal wall, patients symptomatic
  • Invasive intestinal: parasite causes intestinal manifestations
  • Invasive extraintestinal: parasite spreads to distant organs and causes extraintestinal manifestations
