Demand for high-quality drinking and recreational water rises exponentially owing to global demographic growth in the human population, reinforcing an urgent need for microbiologically safe reclaimed water. However, constructed wetlands, implemented into municipal wastewater treatment, may not provide substantial remediation for human protozoan enteropathogens such as Cryptosporidium, Giardia and human-virulent microsporidia. Improving reclaimed water quality by lowering faecal coliforms is not a sound solution for these pathogens. Current advances in molecular technology can benefit public health in developing and developed countries by changing the conceptual research framework for wastewater-receiving wetlands from 'pathogen removal' to 'pathogen source tracking' efforts.
由于全球人口的增长，对高质量饮用水和娱乐用水的需求呈指数级上升，这凸显了对微生物安全再生水的迫切需求。然而，应用于城市污水处理的人工湿地可能无法对诸如隐孢子虫、贾第虫和具有人致病性的微孢子虫等人类原生动物肠道病原体进行有效治理。通过降低粪便大肠菌群来改善再生水质量对于这些病原体而言并非可靠的解决方案。分子技术的当前进展可以通过将接纳废水的湿地的概念性研究框架从“去除病原体”转变为“追踪病原体来源”的工作，使发展中国家和发达国家的公众健康受益。
