Abstract

The use of antimicrobial drugs in food animals, specifically drugs in classes used also in human medicine, remains a contentious public health issue. Increasing concern with antimicrobial resistance has also enhanced the need for research that measure the impacts of utilizing antimicrobial drugs on antimicrobial resistance. The objective of this study was to longitudinally quantify E. coli resistant to ciprofloxacin and ceftiofur in calves treated with enrofloxacin or tulathromycin for control of bovine respiratory disease in high risk calves.
