A parasitologic survey of a low socioeconomic level community from Mara County, Zulia State, Venezuela was done. A single stool specimen per person from 327 individuals was obtained and examined by hematoxylin stained fecal smears and formol-ether concentrates. The overall parasitic infection rate was 92%. Multiple infections were present in 89% of the population. The amebic prevalence rate (APR) was 41.5%. Entamoeba histolytica was found in 9.2% of the individuals, most of them being asymptomatic. Haematophagous trophozoites were observed in two symptomatic cases. Entamoeba coli was the most frequent protozoan (23.5%). The APR was high in all groups. In males it was higher in 7-12 year old children and adolescents, and in females it was higher in adults. Giardia lamblia was the most frequent flagellate (18%) and among the helminths, Trichuris trichiura (82.8%) and Ascaris lumbricoides (74.6%). The high rates of parasitic infection, multiple parasitosis and amebic prevalence reflect the low socioeconomic conditions in the population.
对委内瑞拉苏利亚州马拉开波县一个社会经济水平较低的社区进行了寄生虫学调查。从327个人那里每人获取了一份粪便标本，通过苏木精染色粪便涂片和甲醛-乙醚浓缩法进行检查。总体寄生虫感染率为92%。89%的人群存在多重感染。阿米巴患病率（APR）为41.5%。在9.2%的个体中发现了溶组织内阿米巴，其中大多数无症状。在两例有症状的病例中观察到吸血滋养体。结肠内阿米巴是最常见的原生动物（23.5%）。所有组的APR都很高。在男性中，7至12岁儿童和青少年的APR较高，在女性中，成年人的APR较高。蓝氏贾第鞭毛虫是最常见的鞭毛虫（18%），在蠕虫中，鞭虫（82.8%）和蛔虫（74.6%）最为常见。寄生虫感染、多重寄生虫病和阿米巴患病率的高比率反映了该人群的低社会经济状况。
