  • Amebiasis is an intestinal disease caused by protozoa and is observed only in humans.
  • The source of infection is a sick or carrier of amoebas. A person becomes infected by drinking contaminated water, food poisoning, or by household contact (through dirty hands). 
  • Amoeba cysts that are at rest enter the intestine, where they are converted into a translucent form of the pathogen. 
  • This form either lives permanently in the intestine, forming the carriage of amoebiasis or penetrates the intestinal wall and turns into a tissue form.
  • Amoebiasis is caused by the single-celled organism Entamoeba histolytica. It has 2 stages of development – vegetative and cyst (resting phase). The microorganism is excreted in the feces of the patient or carrier and enters the environment.
  • Causes of amoebiasis include unsatisfactory living conditions; hygienic illiteracy, weakening of the immune system, and improper nutrition.
  • Symptoms of amoebiasis usually occur 1 to 1.5 months after infection. Like elevated body temperature, irritability, fatigue, sleep disorders, loss of appetite, and headaches.
