Amoeba protozoa, or amoebas, are parasitic amoebas that live in human body cavities. Amebas include Ameba lysogena, Ameba Dispera, Ameba Moskovsky, and Ameba colonicus, but only Ameba lysogena can cause human disease. The encapsulation of amoeba is infectious, and usually the encapsulation is excreted in the feces of amoeba-infected people, which is then transmitted to healthy people, mainly through oral infection, especially in malnourished people, immunocompromised people, and people who receive immunotherapeutic agent treatment, etc. The incidence of this disease is higher. The invasion of amoeba into the human body can mostly lead to severe amoebic dysentery, amoebic liver disease or encephalopathy. Treatment of amebiasis is aimed at removing the encapsulated bodies and trophozoites from the intestinal lumen and preventing further infections. Consultation with a medical professional is recommended.
