Amoebiasis: Causes, Symptoms and Treatments

Amoebiasis: What is it?

 Amoebiasis is an infection of intestines due to microorganisms. In this condition, intestine walls get inflamed due to action of a parasitic microorganism, called Entamoeba histolytica. This microorganism enters the patient’s body system through contaminated food and water. This condition is mostly seen in people living in unhygienic conditions like in areas with poor sanitation.

Food gets contaminated when an infected person touches it with unwashed hands, especially raw vegetables and fruits.

Entamoeba histolytica parasites are passed in faeces of persons infected with it. This kind of infection spreads when the stool is not disposed off in proper hygienic way or infected people do not wash their hands properly after passing stool. These contaminated hands can spread parasites to the foods or surfaces they touch. While changing the nappies of an infant, hands can get contaminated.

Amoebiasis can spread to other internal organs like liver, brain or other vital organs through blood stream.
