Similarity between Human and Chicken<i>Escherichia coli</i>Isolates in Relation to Ciprofloxacin Resistance Status

Abstract

Ciprofloxacin-resistant E. coli may arise de novo in poultry from susceptible progenitors, be transmitted to humans via the food supply, and go on to cause potentially life-threatening infections. If confirmed, these findings would mandate efforts to eliminate this reservoir of drug-resistant pathogens and/or to block their transmission to humans.
