The aim of this study was to compare the rate of parasitism and intestinal parasitism profiles of children who live in relatively proximal communities across the 5 municipalities of the Barranquilla metropolitan area, Colombia.
In total, 986 fecal samples from children aged 1 to 10 were analyzed using a direct method (physiological saline and lugol) and the zinc sulfate flotation technique. A comparative analysis of the parasitism profiles between sampling locations (7 schools and 3 health centers providing growth and development services) was conducted using principal component analysis (PCA). The presence of Taenia solium antibodies was evaluated by the enzyme-linked immunosorbent assay method in 269 serum samples from the same group of children.
The overall prevalence of intestinal parasitism was 57.6% (range, 42.1%-77.6%) across the sampling areas. The prevalence of helminthiasis was between 4.1% and 23.7%, and that of intestinal protozoa was between 38.2% and 73.5%. PCA showed that the parasite profiles of each sampling location shared no common characteristics. A total of 3.0% of the serum samples were positive for T. solium antibodies.
The intestinal parasitism profiles between relatively proximal sampling locations with similar geographic conditions were vastly different, indicating the need to study each small ecological niche on a localized scale to develop more cost-effective interventions for controlling intestinal parasitism.
本研究旨在比较哥伦比亚巴兰基亚大都市区5个市相对邻近社区儿童的寄生虫感染率和肠道寄生虫感染情况。
采用直接法（生理盐水和卢戈氏碘液）和硫酸锌漂浮技术，对986份1至10岁儿童的粪便样本进行分析。使用主成分分析（PCA）对采样地点（7所学校和3个提供生长发育服务的健康中心）之间的寄生虫感染情况进行比较分析。采用酶联免疫吸附测定法对同一组儿童的269份血清样本进行猪带绦虫抗体检测。
各采样地区肠道寄生虫总体感染率为57.6%（范围42.1%-77.6%）。蠕虫感染率在4.1%至23.7%之间，肠道原生动物感染率在38.2%至73.5%之间。主成分分析表明，各采样地点的寄生虫感染情况没有共同特征。共有3.0%的血清样本猪带绦虫抗体呈阳性。
地理条件相似的相对邻近采样地点之间的肠道寄生虫感染情况差异很大，这表明需要在局部范围内研究每个小生态位，以制定更具成本效益的肠道寄生虫控制干预措施。
