[Effect of indirect fluorescent antibody test for the diagnosis of amoebiasis].
Indirect fluorescent antibody test (IFAT) was performed by the method of [symbol: see text] (1971) with some slight modifications for the diagnosis of amoebiasis. The antigen used was prepared from 48-hour culture of Entamoeba histolytica (strains G2, G3, and G5) in LAS diphasic medium and only those amoebae clinging the culture were collected. The serum samples or blood drops on filter paper were positive by the improved IFAT in all of the 54 cases of amoebic liver abscess and the positive reactions of most cases were very marked. Of 23 cases of acute amoebic dysentery, 19 were positive, the positive rate being 82.6%. The results also show that 42 cases of other diseases and 40 healthy persons were all negative.
