A total of 77 mentally retarded male inpatients residing in a psychiatric institution in northern Italy were screened for the presence of stool parasites, Entamoeba histolytica particularly. Parasitological stool examination showed Entamoeba spp. (E. histolytica and/or E. dispar) in 26 cases (33.7%). In vitro culture on Robinson's medium was positive in 16 cases (61.1%); in 11 cases we could stabilize and clone the isolates and proceed to electrophoretic assays. In all cases, patterns of pathogenic zymodemes were found (zymodeme II, 3 isolates; zymodeme XII, 4 isolates; zymodeme XIV, 4 isolates). All isolates were therefore identified as E. histolytica.
对居住在意大利北部一家精神病院的77名男性智障住院患者进行了粪便寄生虫筛查，尤其检查了溶组织内阿米巴。粪便寄生虫学检查显示，26例（33.7%）存在阿米巴属（溶组织内阿米巴和/或迪斯帕内阿米巴）。在罗宾逊培养基上进行的体外培养，16例（61.1%）呈阳性；11例中，我们能够稳定分离株并进行克隆，然后进行电泳分析。在所有病例中，均发现了致病酶谱型（酶谱型II，3株分离株；酶谱型XII，4株分离株；酶谱型XIV，4株分离株）。因此，所有分离株均被鉴定为溶组织内阿米巴。
