Water filtration is a common strategy of water sanitation in resource-poor tropical settings. Here, we assessed the intermediate term effect of this preventive procedure including specific filter-related as well as general hygiene training on the molecular detection of enteric pathogens in stool samples from Colombian Indigenous people. From a total of 89 individuals from an Indigenous tribe called Wiwa, stool samples were assessed by real-time PCR for enteropathogenic microorganisms prior to the implementation of water filtration-based infection prevention. Three years after the onset of the preventive strategy, a follow-up assessment was performed. A significantly beneficial effect of water filtration could be shown for spp. only ( = 0.035) and a tendency ( = 0.059) for . No hints for effects on the gastrointestinal shedding of , , spp., spp., spp./enteroinvasive , , , , and spp. were seen. In conclusion, the study indicates that water filtration can only be an element of a multi-modal hygiene concept to reduce enteric pathogen carriage in inhabitants of resource-poor tropical settings in spite of tendencies of beneficial effects.
在资源匮乏的热带地区，水过滤是一种常见的水卫生策略。在此，我们评估了这一预防措施的中期效果，包括与过滤器相关的特定培训以及一般卫生培训，对哥伦比亚原住民粪便样本中肠道病原体分子检测的影响。从一个名为维瓦的原住民部落的89个人中，在实施基于水过滤的感染预防措施之前，通过实时PCR对粪便样本中的肠道致病微生物进行了评估。预防策略实施三年后，进行了随访评估。仅对[具体菌种]显示出水过滤有显著有益效果（P = 0.035），对[另一菌种]有趋势性效果（P = 0.059）。未发现对[其他多种菌种]胃肠道排菌有影响的迹象。总之，该研究表明，尽管有有益效果的趋势，但水过滤只能作为多模式卫生概念的一个要素，以减少资源匮乏的热带地区居民肠道病原体的携带。
