How can we win the race against antibiotic resistance? We ask an expert
Published on 18/11/2025

For years we’ve been reading about the ability of certain bacteria to resist traditional antibiotics. “Nightmare bacteria”, superbugs, multi-resistance are all concepts that are becoming increasingly common and reflect the same reality: the impossibility of treating bacterial infections with antimicrobial molecules.
In fact, bacteria become resistant due to random mutations. If we stop an antibiotic treatment too early, they have a greater chance to mutate; and if we use antibiotics unnecessarily, we encourage resistant strains to survive and multiply. This creates a vicious circle that jeopardises the effectiveness of our treatments.
Today we’re talking to researcher Marc Torrent, Senior Lecturer in the Department of Biochemistry and Molecular Biology at the Autonomous University of Barcelona,
