Mapping 100 years of bacterial evolution reveals key spreaders of antibiotic resistance
Medicamente
Wellcome Trust Sanger Institute Sep 25 2025 The genetic culprits responsible for the spread of multidrug resistance (MDR) in bacteria have been identified by new research mapping 100 years of bacterial evolution. Experts at the Wellcome Sanger Institute, the University of Bath, the UK Health Security Agency (UKHSA) and their collaborators, analyzed over 40,000 plasmids from historical and present-day bacterial samples taken across six continents, the largest dataset of its kind. Plasmids are
