During a five-year period at The New York Hospital, Entamoeba histolytica was identified in the stools of 20 men who had not traveled outside the New York area. All of the patients were found subsequently to homosexual. During this same period amebiasis was diagnosed in 30 men who had traveled; only two were homosexual. Of ten patients with E histolytica infection seen during the first year of this study, none were homosexual whereas eight of 11 patients in the fifth year were homosexual, suggesting a gradual increase during this period of this disease in the homosexual community.
在纽约医院的五年期间，在20名未曾离开纽约地区的男性粪便中发现了溶组织内阿米巴。所有这些患者后来被发现是同性恋者。在同一时期，30名有过旅行经历的男性被诊断出患有阿米巴病；其中只有两人是同性恋者。在本研究的第一年见到的10名溶组织内阿米巴感染患者中，没有同性恋者，而在第五年的11名患者中有8名是同性恋者，这表明在此期间该疾病在同性恋群体中的发病率逐渐上升。
