[The enzyme-linked immunosorbent assay (ELISA) in the diagnosis of amoebiasis (author's transl)].

An enzyme-linked immunosorbent assay (ELISA) technique as an aid to the detection of antibodies to Entamoeba histolytica has been evaluated in four groups of 39 individuals. Results were positive in 15 patients with amoebic dysentery harboring trophozoites of Entamoeba histolytica, in their stools; negative in 6 patients with enteric symptoms whose faeces contained neither trophozoites nor cysts of Entamoeba histolytica, in 8 patients with other parasitic diseases in whom clinical examination was not indicative of infection with Entamoeba histolytica, and in 10 sera from blood-donors. The ELISA has been shown to be a sensitive method of detecting antibodies to entamoeba histolytica.
