El rol de los plásmidos en la resistencia a antibióticos – DW – 26/09/2025

Research analyzing a century of bacterial evolution reveals that a small minority of plasmids drives the global spread of antimicrobial resistance. By examining samples dating back to 1917, scientists discovered that these mobile genetic structures acquired resistance genes as antibiotic use became widespread. This highlights how human medical practices have fundamentally reshaped bacterial genetics, turning previously benign elements into dangerous vectors for multidrug resistance. The current crisis is largely fueled by a specific group of modern plasmids that combine resistance to both first-line and last-resort antibiotics. These structures emerged through the integration of resistance genes or the fusion of different plasmids. Because these few plasmids are responsible for most resistance cases, they represent a critical focal point for understanding and mitigating the ongoing public health threat that causes significant mortality worldwide. This study is highly relevant to open data because it demonstrates the immense value of historical biological datasets for modeling future trends. By making century-long genomic records available and analysable, researchers can develop evolutionary models to predict outbreaks and inform health policies. Open access to such comprehensive longitudinal data enables the scientific community to better anticipate antimicrobial resistance patterns and guide effective global health interventions.
