摘要

为了探索低收入、人口稠密的城市地区饮用水污染的来源和相关风险，我们于 2019 年在肯尼亚内罗毕收集了人类粪便、驯养动物粪便以及源水和储存的饮用水样本，并使用微生物源追踪（MST）和肠道病原体 TaqMan 阵列卡（TAC）对其进行了分析。我们在这一环境中建立了宿主与病原体之间的关系，包括在狗粪便中检测到志贺氏杆菌和诺罗病毒--它们通常与人类有关。我们使用指示性大肠杆菌 (E.coli)、MST 标记和 TAC 评估了储存水和源饮用水的质量，在饮用水中检测到了在特定动物粪便中也能检测到的病原体目标。这项工作强调了进一步评估宿主-病原体关系和病原体传播方向的必要性，以预防与不安全饮用水和家畜饲养相关的疾病负担。

Enteric Pathogens in Humans, Domesticated Animals, and Drinking Water in a Low-Income Urban Area of Nairobi, Kenya

To explore the sources of and associated risks with drinking water contamination in low-income, densely populated urban areas, we collected human feces, domesticated animal feces, and source and stored drinking water samples in Nairobi, Kenya in 2019; and analyzed them using microbial source tracking (MST) and enteric pathogen TaqMan Array Cards (TACs). We established host–pathogen relationships in this setting, including detecting Shigella and Norovirus─which are typically associated with humans─in dog feces. We evaluated stored and source drinking water quality using indicator Escherichia coli (E. coli), MST markers, and TACs, detecting pathogen targets in drinking water that were also detected in specific animal feces. This work highlights the need for further evaluation of host–pathogen relationships and the directionality of pathogen transmission to prevent the disease burden associated with unsafe drinking water and domestic animal ownership.
