Fluoroquinolones are important antimicrobial drugs used to treat humanSalmonella infections, and resistance is rare in the United States for isolates from human and animal sources. Recently, a number ofSalmonella isolates from swine cecal contents and retail pork products from National Antimicrobial Resistance Monitoring System (NARMS) surveillance exhibited decreased susceptibility to ciprofloxacin. We identified twoqnrB19 quinolone resistance plasmids that are predominantly responsible for this phenomenon and found them distributed among severalSalmonella serotypes isolated throughout the United States.
