A new study led by the University of Oxford has found that natural evolution of antibiotic resistance genes has maintained resistance in bacteria despite a reduction in the use of antibiotics. The findings demonstrate the importance of understanding the regulatory evolution of resistance genes to strategically combat AMR.
