Sera collected from 606 children of low socioeconomic level attending the University and Children's hospitals in Maracaibo, Venezuela, were screened for serologic evidence of Entamoeba histolytica infection, employing the indirect hemagglutination test. The seropositivity rate was 7.7%. Most of the positive sera showed low titers (1:128-1:256). The overall prevalence of positive reactors increased with age. Stool examinations done on 516 children revealed cysts or trophozoites of E. histolytica in 4.4%.
从委内瑞拉马拉开波市大学医院和儿童医院就诊的606名社会经济水平较低的儿童中采集血清，采用间接血凝试验筛查溶组织内阿米巴感染的血清学证据。血清阳性率为7.7%。大多数阳性血清滴度较低（1:128 - 1:256）。阳性反应者的总体患病率随年龄增长而增加。对516名儿童进行的粪便检查显示，4.4%的儿童粪便中有溶组织内阿米巴的包囊或滋养体。
