Intestinal parasitic infections are among the most common infections and health problems worldwide. Due to the lack of epidemiologic information of such infections, the prevalence of, and the risk factors for, enteric parasites were investigated in residents of Roudehen, Tehran Province, Iran.
In this cross-sectional study, 561 triple fecal samples were collected through a two-stage cluster-sampling protocol from Jun to Dec 2014. The samples were examined by formalin-ether concentration, culture, and with molecular methods.
The prevalence of enteric parasites was 32.7% (95% CI 27.3-38). sp. was the most common intestinal protozoan (28.4%; 95% CI 23.7-33.0). The formalin-ether concentration and culture methods detected sp., , , , , , , and . Single-round PCR assay for complex were identified and . was not observed in any specimen. Multivariate analysis showed a significant association of parasites with water source and close animal contact. There was no correlation between infections and gender, age, occupation, education, or travel history. Protozoan infections were more common than helminth infections.
This study revealed a high prevalence of enteric protozoan parasite infection among citizens of Rodehen. As most of the species detected are transmitted through a water-resistant cyst, public and individual education on personal hygiene should be considered to reduce transmission of intestinal parasites in the population.
肠道寄生虫感染是全球最常见的感染和健康问题之一。由于缺乏此类感染的流行病学信息，对伊朗德黑兰省鲁德亨居民肠道寄生虫的患病率及其危险因素进行了调查。
在这项横断面研究中，通过两阶段整群抽样方案于2014年6月至12月收集了561份三联粪便样本。样本通过福尔马林-乙醚浓缩法、培养法以及分子方法进行检测。
肠道寄生虫的患病率为32.7%（95%置信区间27.3 - 38）。 属是最常见的肠道原生动物（28.4%；95%置信区间23.7 - 33.0）。福尔马林-乙醚浓缩法和培养法检测到了 属、 属、 属、 属、 属、 属、 属和 属。针对 复合体的单轮PCR检测鉴定出了 和 。在任何样本中均未观察到 。多变量分析显示寄生虫与水源和密切动物接触之间存在显著关联。感染与性别、年龄、职业、教育程度或旅行史之间无相关性。原生动物感染比蠕虫感染更常见。
本研究揭示了鲁德亨市民中肠道原生动物寄生虫感染的高患病率。由于检测到的大多数物种是通过耐水包囊传播的，应考虑开展关于个人卫生的公众和个人教育，以减少人群中肠道寄生虫的传播。
