摘要

在过去50年中,在河流中观察到的低水流量的减少、水温和其他参数的升高表明,与气候变化和/或人类活动有关的化合物和污染物的浓度正在发生(没有发现它们各自的贡献)。这些影响发生在河流已经受到许多污染物混合物(杀虫剂、药物和其他)影响的情况下。作者现在表明,这些污染物混合物——以目前发现的环境浓度——通过可能对致病菌的毒力产生影响,对人类健康构成威胁。虽然鼠伤寒沙门氏菌的某些基因可能不会增加风险,但暴露于更高浓度的鸡尾酒(五倍浓度)可能会放大某些毒力因子,如铜绿假单胞菌H103的运动性。研究结果表明,污染混合物对某些水传播致病菌的毒力潜力有影响,即使在目前在河流中观察到的浓度下也是如此。

The risk of bacterial virulence in the face of concentrated river pollution
The decrease in low-water flows and the increase in water temperature and other parameters as observed in the rivers over the last 50 years suggest that a concentration of compounds and pollutants is taking place, in connection with climate change and/or anthropisation (without discerning their respective contributions). These effects occur in a context where the rivers are already impacted by the presence of many pollutant cocktails (pesticides, drugs, and others). The authors now show that these pollutant cocktails – at the environmental concentrations currently found – constitute a threat to human health through their possible effects on the virulence of pathogenic bacteria. While certain genes of Salmonella Typhimurium may not experience an increased risk, the exposure to more concentrated cocktails (at a five-fold concentration) could potentially amplify certain virulent factors such as the motility of Pseudomonas aeruginosa H103. The findings indicate that pollution mixtures have an effect on the virulence potential of certain waterborne pathogenic bacteria, even at concentrations currently observed in rivers.
