Antigen consists of a crude soluble extract of axenically cultured organisms. The EIA test detects antibody specific for E. histolytica in approximately 95% of patients with extraintestinal amebiasis, 70% of patients with active intestinal infection, and 10% of asymptomatic persons who are passing cysts of E. histolytica. If antibodies are not ...

Nov 22, 2023 · Intestinal amebiasis is caused by the protozoan Entamoeba histolytica. There are four species of intestinal amebae with identical morphologic characteristics: E. histolytica, E. dispar, E. moshkovskii, and E. bangladeshi [ 1,2 ]. Most symptomatic disease is caused by E. histolytica; E. dispar is generally considered nonpathogenic.
Oct 6, 2022 · Habitat: Trophozoites of E. histolytica live in the mucosal and submucosal layers of the large intestine of man. Life cycle of Entamoeba histolytica has two-stage: motile trophozoite and non-motile cyst. Trophozoites are found in intestinal lesions, extra-intestinal lesions, and diarrheal stools whereas cyst predominates in non-diarrheal stools.
