Abstract excerpt
It is thought that antimicrobial resistance imposes a fitness cost on bacteria, so that a reduction in antimicrobial use may reduce the incidence of resistant bacteria. The objectives of the present study were to determine (1) whether multidrug resistant (MDR) Escherichia coli field strains with different plasmid profiles show disparate plasmid loss when grown over time without selection pressure; (2) whether the...
