ESBL-producing <i>Escherichia coli</i> in wastewater from German slaughterhouses.

ABSTRACT: The increasing prevalence of ESBL-producing Escherichia (E.) coli (ESBL-E. coli) poses a significant threat to human and animal health, with livestock identified as a critical reservoir. This study examined the occurrence and diversity of ESBL-E. coli in wastewater from four German slaughterhouses (pig and poultry) over two sampling periods. The primary objective of the study was to determine whether these facilities have a persistent colonization of AMR bacteria or whether their presence fluctuates daily depending on which animals are processed. Using selective media and subsequent whole-genome sequencing, 47 wastewater samples were analyzed and 86 ESBL-E. coli strains were isolated, 40 of which were multidrug-resistant (MDR). Specifically, 27 out of 37 isolate
