A study today by an international team of scientists has found more evidence of antibiotic resistance in urban wastewater.
In the study, published in Science Advances, the researchers analyzed antibiotic resistance genes in urban wastewater collected at wastewater treatment plants in seven European countries and found that the amount of resistance genes was higher in the wastewater from countries with higher antibiotic use and aligned with the levels of antibiotic resistance found in clinical isolates in the countries.
The results are consistent with the north-to-south pattern that’s been observed in studies of antibiotic resistance and consumption in Europe.
The genes that were detected conferred resistance to several classes of antibiotics, including genes that confer multidrug resistance and are of high concern in clinical settings. The study also identified mobile genetic elements that enable bacteria to share and spread resistance.
