The prevalences of Entamoeba histolytica and other intestinal parasites were assessed in a suburban community of Maracaibo, Venezuela, by examination of a stool specimen from each of 342 individuals, using iron-haematoxylin stained faecal smears and formalin-ether concentration. The overall parasitic infection rate was 80.4%, and 65.8% of the population had multiple infections. The overall amoebic infection rate, which was highest in female adults, averaged 39.7%. The E. histolytica infection rate was 8.7% and most of those infected were passing cysts. Entamoeba polecki was observed in two samples. Amongst the protozoa, Entamoeba coli was observed most frequently (24.8%) and Giardia lamblia was the predominant pathogen (13.0%). Trichuris trichiura (71.9%) and Ascaris lumbricoides (54%) were the most common parasites, particularly in school-children. The high rates of parasitic and multiple infections reflect the low socio-economic status of the community studied.
通过对委内瑞拉马拉开波一个郊区社区342人的粪便样本进行检查，采用铁苏木精染色粪便涂片和福尔马林 - 乙醚浓缩法，评估了溶组织内阿米巴和其他肠道寄生虫的流行情况。总体寄生虫感染率为80.4%，65.8%的人群有多重感染。总体阿米巴感染率在成年女性中最高，平均为39.7%。溶组织内阿米巴感染率为8.7%，大多数感染者排出包囊。在两个样本中观察到波列基内阿米巴。在原生动物中，结肠内阿米巴最常被观察到（24.8%），蓝氏贾第鞭毛虫是主要病原体（13.0%）。鞭虫（71.9%）和蛔虫（54%）是最常见的寄生虫，尤其在学童中。寄生虫和多重感染的高发生率反映了所研究社区的社会经济地位较低。
