One isolate from dog A was of phylogroup A/ST410/CTX-M-15/TEM-1; one from dog B was of phylogroup B1/ST533/CTX-M-15/TEM-1; one from dog C was of phylogroup D/ST648/CTX-M-15. All ESBL producers were resistant to ampicillin, cephalexin, cefalotin, cefpodoxime, ceftiofur, enrofloxacin, marbofloxacin, and trimethoprim/sulfamethoxazole, but were susceptible to imipenem and amoxicillin/clavulanic acid. <em>E. coli</em> of ST533 carrying <em>bla</em><sub>CTX-M-15</sub> were first detected in pet dogs in China.</p> <p class="SmallText">Conclusions: Collectively, the findings could expand our knowledge about the prevalence and characterization of ESBL-producing <em>E. coli</em> urinary tract isolates in pet dogs in China.</p> ER -
