This study investigates the presence and spread of antibiotic-resistant <i>E. coli</i> in a Swedish urban water system, with much higher levels near a wastewater treatment plant (WWTP), suggesting its role in spreading these bacteria. All tested bacterial strains were resistant to multiple antibiotics, with many strains assigned to lineages linked to human infections. This highlights the need for better wastewater treatment to reduce environmental and public health risks.

本研究针对瑞典城市水系统中耐药性大肠埃希菌（E. coli）的存在与传播情况开展调查，发现污水处理厂（WWTP）周边的耐药菌水平显著更高，提示该设施在这类细菌的传播过程中扮演了重要角色。所有受试菌株均对多种抗生素产生耐药性，其中多数菌株被归为与人类感染相关的进化谱系。该研究结果凸显了优化污水处理工艺的必要性，以降低其对环境与公众健康造成的风险。
