MCQ on Amoebiasis with Answers Pdf:

• 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.
