Significant Impact Group(s): AMU reduction strategies \ Monitoring and surveillance
Species targeted: Dairy;
Age: Young;Adult;
Outcome Parameter(s): prevalence of extended-spectrum and AmpC β-lactamase-producing Escherichia coli (ESBL/AmpC-EC)
Summary: Between 2011 and 2013, the period during which the use of 3rd- and 4th-generation cephalosporins was minimized, the between-herd prevalence of resistant E. coli expressing ESBL/AmpC-genes in Dutch dairy herds declined significantly. Calves were found to have both, a much higher individual animal prevalence and a higher level of shedding than young stock and cows. The most sensitive approach to find ESBL/AmpC positive E. coli in Dutch dairy herds is through collecting samples from individual young calves.
