Amoebic sickness refers to an illness caused by an infection with amoebas, which are single-celled organisms that can infect the human body. The most common form of amoebic sickness is amoebiasis, which is caused by the parasite Entamoeba histolytica. Symptoms of amoebic sickness can include diarrhea, abdominal pain, and fever. In severe cases, the infection can lead to complications such as liver abscesses or intestinal perforation. Amoebic sickness is typically treated with antibiotics or antiparasitic medications.
