Data were obtained in 10 patients with amebic dysentery at Osaka Socio-Medical Center hospital during the period from April 1985, to April 1989. All of the patients were male, and their average age was 41 years old. In the past history, all of them had never gone to foreign country, and 7 patients had the habit of homosexual love. In the serological test, positive rate of antiamebic antibody was 100% (6/6) by agar gel diffusion, that of antibody of Toreponema pallidum was 60% (6/10) by TPHA, but anti AIDS antibody was not detected (0/3) by HIV. Detectability of Entoamoeba hystolitica was 70% (7/10) in stool, 50% (2/4) in liver abscess, 25% (1/4) in biopsied specimens of rectal mucosa. Then, we fund that the serological test for antiamebic antigen was useful for diagnosis of this disease, and suspected that homosexual contact contributed to the infection of E. hystolitica.
1985年4月至1989年4月期间，在大阪社会医学中心医院对10例阿米巴痢疾患者进行了数据采集。所有患者均为男性，平均年龄41岁。既往史方面，他们均未曾出过国，7例有同性恋习惯。血清学检测中，琼脂凝胶扩散法检测抗阿米巴抗体阳性率为100%（6/6），梅毒螺旋体血凝试验检测梅毒抗体阳性率为60%（6/10），但HIV检测抗艾滋病抗体未检出（0/3）。溶组织内阿米巴在粪便中的检出率为70%（7/10），在肝脓肿中的检出率为50%（2/4），在直肠黏膜活检标本中的检出率为25%（1/4）。然后，我们发现抗阿米巴抗原的血清学检测对该病诊断有用，并怀疑同性恋接触导致了溶组织内阿米巴感染。
