Day care centers play an important social role in children's early education and development. The objective of this study was to investigate the frequency of intestinal parasitic infections and infection with Toxocara spp. in children from a day care center in the city of Rio Grande, Rio Grande do Sul, Brazil. Methods: The study was conducted using fecal samples from 50 children, ages three to six years, using Ritchie, Faust, Rugai, and Kinyoun's techniques. A closed and structured epidemiological questionnaire was used to collect data from the parents/guardians of the children. Serological studies for detection of antibodies to Toxocara spp. by immunoenzymatic assays using Toxocara excretion and secretion antigen (TES) were conducted on sera collected from 41 children. Results: The frequency of enteroparasites was 18%, with 43.9% of the children testing seropositive for Toxocara spp. Low family income and low literacy levels of parents/guardians were common factors between the families of the parasite-positive children. For the children who tested positive for Toxocara spp., most of the parents/guardians reported using only water for sanitizing raw vegetables and fruits. Conclusions: The high seropositivity rates for Toxocara spp. indicate that children were exposed to this parasite, and it is important to reduce the risk of infection. In addition, the seropositivity for enteroparasites and the interviews with the parents/guardians indicate the need to educate the studied population regarding the modes of intestinal parasite transmission and the prophylactic measures needed to prevent their dissemination.
日托中心在儿童早期教育和发展中发挥着重要的社会作用。本研究的目的是调查巴西南里奥格兰德州里奥格兰德市一家日托中心儿童肠道寄生虫感染及弓蛔虫属感染的频率。方法：本研究采用来自50名3至6岁儿童的粪便样本，运用里奇、浮士德、鲁盖和金扬氏技术。使用封闭式结构化流行病学问卷从儿童的父母/监护人处收集数据。对从41名儿童采集的血清进行血清学研究，通过使用弓蛔虫排泄和分泌抗原（TES）的免疫酶测定法检测弓蛔虫属抗体。结果：肠道寄生虫感染率为18%，43.9%的儿童弓蛔虫属血清学检测呈阳性。寄生虫检测呈阳性儿童的家庭中，家庭收入低和父母/监护人文化程度低是常见因素。对于弓蛔虫属检测呈阳性的儿童，大多数父母/监护人报告仅用水清洗生蔬菜和水果。结论：弓蛔虫属的高血清阳性率表明儿童接触了这种寄生虫，降低感染风险很重要。此外，肠道寄生虫的血清阳性以及与父母/监护人的访谈表明，需要对研究人群进行关于肠道寄生虫传播方式以及预防其传播所需预防措施的教育。
