Ascariasis is caused by a digenetic parasite while amoebiasis is caused by a monogenetic parasite.
Ascariasis is caused by a parasite that lives in small intestine while amoebiasis is caused by a parasite that lives in large intestine.
Ascariasis causes blockage of intestinal passage while amoebiasis causes blockage of lymphatic vessels.
Solution:Ascariasis is caused by Ascaris lumbricoides which lives in small intestine while amoebiasis is caused by Entamoeba histolytica which lives in large intestine. Both are foodborne diseases. Both are monogenetic parasites (complete life cycle in a single host). Blockage of lymphatic vessels is caused by filariasis.
