Abstract：
BACKGROUND Hymenolepiasis is a globally prevalent zoonosis of the monoxenic cycle. Humans acquire the disease through fecal-oral transmission by ingesting food or water with infective eggs from infected rodents. This report presents 3 cases of hymenolepiasis in children, due to zoonotic transmission from rodents and presumably associated with the consumption of powdered milk contaminated with infective eggs of Hymenolepis nana, and shows that awareness and early diagnosis contributed to timely treatment of the disease. CASE REPORT Three children, aged 9, 12, and 13 years, living in a marginal urban area of Guayaquil, Guayas province, Ecuador, presented symptoms of diarrhea, low body weight, abdominal discomfort, anorexia, paleness, and anal itching. Subsequently, their fecal samples were analyzed by direct coproparasitic methods, flotation and sedimentation with centrifugation using saline solution; the presence of H. nana eggs was determined. Blood biometry was performed. Further, 10 rodents were captured and necropsied to obtain intestinal contents. The powdered milk consumed by the children was analyzed, the same powder that contained rodent feces. Subsequently, these were studied with the above-mentioned coproparasitic methods. H. nana eggs were identified in the 6 trapped rodents, the powdered milk, and the feces of rodents found in the milk powder. CONCLUSIONS Hymenolepiasis can affect populations of endemic areas. In this case, the disease was identified in 3 children, who were diagnosed with eosinophilia and anemia. Additionally, the presence of H. nana eggs in captured rodents and in powdered milk was determined, indicating that the community was exposed to this zoonotic disease.
摘要：
背景技术膜状上皮病是一种全球流行的单氧循环人畜共患病。人类通过从被感染的啮齿动物中摄取具有感染卵的食物或水，通过粪便-口腔传播获得疾病。本报告介绍了3例儿童内膜上皮病，由于来自啮齿动物的人畜共患传播，并且可能与食用被感染的虫卵污染的奶粉有关。并表明意识和早期诊断有助于及时治疗该疾病。案例报告三个孩子,9岁、12岁和13岁，生活在瓜亚基尔的边缘城区，瓜亚斯省,厄瓜多尔,出现腹泻的症状，体重低,腹部不适,厌食症,苍白,和肛门瘙痒。随后，他们的粪便样本通过直接共寄生虫方法进行分析，使用盐溶液进行浮选和离心沉降；确定了H.nana卵的存在。进行血液生物测定。Further,捕获10只啮齿动物并进行尸检以获得肠内容物。分析了孩子们食用的奶粉，含有啮齿动物粪便的相同粉末。随后，这些都是用上述的协同寄生方法研究的。在6只被困的啮齿动物中发现了H.Nana卵，奶粉，和在奶粉中发现的啮齿动物的粪便。结论脑膜病可影响流行地区的人群。在这种情况下,在3名儿童中发现了这种疾病，被诊断为嗜酸性粒细胞增多症和贫血.此外,确定了捕获的啮齿动物和奶粉中H.Nana卵的存在，表明该社区暴露于这种人畜共患疾病。
