2.3.5  Amoebic dysentery

Amoebic dysentery, also called amoebiasis, is a disease caused by the protozoa Entamoeba histolytica (Figure 2.8). It is acquired by ingesting infectious cysts (a dormant form of the organism that helps it survive in unfavourable environments) through water or food items that are contaminated.
