Genomic characterization of ESBL/AmpC-producing and high-risk clonal lineages of Escherichia coliand Klebsiella pneumoniaein imported dogs with shelter and stray background

•ESBL/AmpC-carrying Enterobacteriaceae isolated from imported dogs were studied with WGS.•Genes encoding resistance to β-lactams were detected most often.•High-risk clonal lineages E. coliST410 and K. pneumoniaeST307 were observed.•IncF plasmid replicons were often associated with β-lactamase gene blaCTX-M-15.•A third of the E. coliisolates qualified as extraintestinal pathogenic E. coli.
