Broiler Chickens as Source of Human Fluoroquinolone- Resistant Escherichia coli
To investigate feed as a source for fl uoroquinoloneresistant Escherichia coli in broiler chickens, we compared antimicrobial drug–resistant E. coli from broiler feed and broilers with ciprofl oxacin-resistant human clinical isolates by using pulsed-fi eld gel electrophoresis. Feed was implicated as...
