Intestinal parasite infections and polyparasitism are highly prevalent in the most vulnerable populations of developing countries due to environmental, biological and social determinants common in the transmission of parasites. Children between 1 and 15 years of age are the most affected population.
To describe the prevalence and profiles of intestinal polyparasitism in 1 to 15 year-old children from native communities in the Colombian Amazon region.
We used a non-probability sampling of 300 children between 1 and 15 years of age from several rural settlements and the main urban area of Puerto Nariño, Amazonas, Colombia, who participated voluntarily in the study. We obtained fecal samples that were analyzed by the direct method (0.85% saline solution-lugol) and the Kato-Katz technique. The most prevalent polyparasitism profiles were identified using Cohen's kappa coefficient with a 95% confidence interval.
The prevalence of polyparasitism, defined as the presence of at least two intestinal pathogenic parasites, was 84% (95 % CI: 79.35-87.96). Polyparasitism by two or three of the following parasites: Ascaris lumbricoides, Trichuris trichiura, Blastocystis sp., Ancylostoma duodenale and Necator americanus from the Ancylostomatidae family, and Entamoeba histolytica, E. dispar and E. moshkovskii of the Entamoeba complex, had the highest prevalence.
Several intestinal polyparasitism profiles were found, although in most cases fewer than six parasites were involved. Better prevalence estimations and identification of determinant factors will allow to priorize and direct resources to control these infections.
由于寄生虫传播中常见的环境、生物和社会因素，肠道寄生虫感染和多重寄生虫感染在发展中国家最脆弱的人群中极为普遍。1至15岁的儿童是受影响最严重的人群。
描述哥伦比亚亚马逊地区土著社区1至15岁儿童肠道多重寄生虫感染的患病率和特征。
我们采用非概率抽样方法，从哥伦比亚亚马孙省纳里尼奥港的几个农村定居点和主要市区选取了300名1至15岁的儿童，他们自愿参与了这项研究。我们获取了粪便样本，并通过直接法（0.85%盐溶液-卢戈氏碘液）和加藤厚涂片法进行分析。使用科恩kappa系数及95%置信区间确定最常见的多重寄生虫感染特征。
多重寄生虫感染的患病率，即至少存在两种肠道致病寄生虫的情况，为84%（95%CI：79.35 - 87.96）。由以下两种或三种寄生虫引起的多重寄生虫感染最为常见：蛔虫、鞭虫、芽囊原虫、十二指肠钩口线虫和美洲板口线虫（钩口科），以及溶组织内阿米巴、迪斯帕内阿米巴和莫氏内阿米巴（内阿米巴属）。
发现了几种肠道多重寄生虫感染特征，尽管在大多数情况下涉及的寄生虫少于六种。更好地估计患病率并确定决定因素将有助于优先安排和引导资源来控制这些感染。
