E coli in a mexican river. A resistance profile

Bacterial resistance is a public health issue. Since the 2019 pandemic, it has been observed that monitoring microorganisms in rivers provides significant information regarding their distribution and prevalence, making them hot spots for epidemiological surveillance. Therefore, analyzing the presence of E. coli and its antibacterial susceptibility pattern as a sentinel microorganism is of great importance in monitoring bacterial resistance in a river located in central Mexico, where industrial, hospital, and domestic waste flows into the river. This can be very useful as part of surveillance from a one health perspective.细菌耐药性是当前重要的公共卫生挑战。自2019年全球大流行以来，已有研究证实，对河流微生物开展监测可获取其分布与流行特征的关键数据，河流也因此成为流行病学监测的热点区域。鉴于此，以大肠埃希菌（E. coli）作为哨兵微生物，分析墨西哥中部某条接纳工业、医疗与生活污水的河流中该菌的存在情况及其抗菌药物敏感性模式，对于该区域的细菌耐药性监测具有重要价值。从同一健康（One Health）视角来看，此类分析可作为监测工作的核心组成部分，具备显著的应用意义。
