Microbe sample from Escherichia coli
The present study aims to elucidate the prevalence of resistant and/or multidrug resistant faecal E. coli and to investigate whether the two husbandry systems are equally associated with AMU and AMR prevalence. Additionally, isolates exhibiting a noteworthy phenotype are further characterized using whole genome sequencing. This study seeks to contribute to our understanding of heifers in the epidemiology of AMR in Switzerland
