Virulence Characteristics and Phylogenetic Background of Multidrug‐Resistant and Antimicrobial‐Susceptible Clinical Isolates of<i>Escherichia coli</i>from across the United States, 2000–2001

Abstract

These findings argue against a direct link between virulence traits and antimicrobial resistance in E. coli. Instead, they call into question why non-B2 strains are more commonly MDR, with differential exposure to selection pressure (including in agriculture) as one possible explanation.
