背景
环孢子虫在流行地区的传播动态以及与土壤污染相关的因素仍不清楚。环境因素对环孢子虫的影响研究不足，特别是在南美洲，因此对委内瑞拉的一个社区进行了研究，以分析感染的风险因素。
方法
对732人进行了横断面粪便调查。对于环孢子虫的筛查，使用了福尔马林 - 乙酸乙酯浓缩物的抗酸染色涂片以及湿涂片的紫外（UV）落射荧光检查。收集了水（n = 14）、土壤（n = 50）和农产品（n = 77）样本，进行处理并通过紫外落射荧光检查。使用多变量逻辑回归分析数据。
结果
在73名（9.9%）受试者中发现了环孢子虫感染。与感染相关的变量是年龄……
Background Transmission dynamics of Cyclospora cayetanensis in endemic areas and the factors associated with soil contamination remain unclear. The effects of environmental factors on Cyclospora have been insufficiently studied, particularly in South America, thus a Venezuelan community was studied to profile risk factors for infection. Methods A cross-sectional stool survey of 732 individuals was conducted. For Cyclospora screening, an acid-fast-stained smear of formalin-ethyl acetate concentrate and ultraviolet (UV) epifluorescence examination of a wet mount were used. Water (n=14), soil (n=50) and produce (n=77) samples were collected, processed and examined by UV epifluorescence. Data were analysed using multivariate logistic regression. Results Cyclospora infections were identified in 73 (9.9%) subjects. Variables associated with the infection were age
