用生长在ＬＡＳ双相培养基上４８ｈ的贴壁溶组织内阿米巴作抗原和略加修改的等（１９７１）方法进行间接荧光抗体试验。结果５４例阿米巴肝脓肿病人血清或滤纸干血滴全部阳性，且滴度都较高（１：８０－１：２５６０）。２３例阿米巴痢疾患者中，１９例阳性，阳性率为８２．６％；４２例非阿米巴病和４０例正常人血清或滤纸干血滴均阴性。 Indirect fluorescent antibody tests were performed using the M. entacticis Entamoebae grown for 48h on LAS biphasic medium as an antigen with a slight modification (1971). Results All 54 cases of amoebic hepatic abscess were positive in serum or filter paper, and the titers were high (1: 80-1: 2560). Of the 23 patients with amoebic dysentery, 19 were positive, with a positive rate of 82.6%; 42 were non-amoebiasis and 40 normal persons were negative for serum or filter paper dry blood.
