Plain-English summary
A study found that two dogs and two cats in Switzerland had urinary tract infections caused by a type of E. coli that produces extended-spectrum beta-lactamase (ESBL), making it resistant to many antibiotics. The researchers identified eight specific strains of this bacteria from urine samples, which included different genetic types. This is concerning because it shows that these resistant bacteria are affecting pets, and one strain was detected in a dog for the first time. Treatment options may be limited due to the antibiotic resistance, so it's important for pet owners to discuss effective treatments with their veterinarian.

Abstract
Extended-spectrum β-lactamase (ESBL)-producing Escherichia (E.) coli have emerged in human and veterinary medicine. The aim of this study was to investigate the presence of ESBL-producers among uropathogenic E. coli isolated from dogs and cats and to characterize detected ESBL-producing isolates by antibiotic susceptibility testing, identification of ESBL genes, multi-locus sequence typing (MLST), detection of putative virulence genes, and analysis of E. coli phylogroups. Among the 107 E. coli isolates derived from urinary samples (59 from dogs, 40 from cats), eight isolates from four different animals (two dogs, two cats) were found to be ESBL-producers. These isolates were of ST533/CTX-M-15/TEM/phylogroup B1 (four strains from one dog), ST410/CTX-M-15/TEM/phylogroup A (three strains, one from a dog and two from a cat), and ST648/CTX-M-15/phylogroup D (one strain from a cat). In terms of putative virulence factors, all isolates harbored lpfA, sat, and tsh, whereas iss was only detected in strains of ST533. Thus, ESBL-producers were detected among uropathogenic E. coli from Swiss companion animals and the eight CTX-M-15-producing isolates belonged to three sequence types (ST410, ST533, ST648) and three E. coli phylogroups (A, B1, D). For the first time, E. coli of ST533 carrying bla(CTX-M-15) were thereby detected in a dog.
