Multicopy plasmids potentiate the evolution of antibiotic resistance in bacteria

Abstract:

Plasmids are thought to play a key role in bacterial evolution by acting as vehicles for horizontal gene transfer, but the role of plasmids as catalysts of gene evolution remains unexplored. We challenged populations of E. coli carrying blaTEM-1 β- lactamase gene on either the chromosome or a multicopy plasmid (19/cell) with increasing concentrations of ceftazidime. The plasmid accelerated resistance evolution by increasing the rate of appearance of novel TEM-1 mutations conferring resistance...
