Plain-English summary
A 5-year-old dog developed severe vomiting and bloody diarrhea after undergoing surgery and sadly passed away despite treatment efforts. A postmortem examination revealed that the dog had hemorrhagic gastroenteritis and colitis caused by a dangerous strain of bacteria that was resistant to multiple antibiotics. This strain produced harmful toxins and was able to resist common treatments like amoxicillin and enrofloxacin. The case highlights the risks of infections that can affect both pets and their owners, emphasizing the importance of monitoring for severe gastrointestinal symptoms after surgery.

Abstract
is a member of the familyand is a commensal in the intestine of many animals as well as humans. Most strains are of low virulence. A dog developed vomiting and hemorrhagic diarrhea after surgery and died despite treatment. Postmortem examination revealed hemorrhagic gastroenteritis and colitis. A multidrug-resistant, with virulence factors Shiga-toxin-producing gene, stx2,gene, and cytotoxic necrotic factors CNF-1 and CNF-2, was isolated from internal organs.can easily acquire new genes for virulence factors and antimicrobial resistance as demonstrated by this isolate with characteristics of both enterohemorrhagicand necrotoxigenic. In addition, the isolate was resistant to all beta-lactam antibiotics tested, as well as to enrofloxacin by a disk diffusion methodology. Broth-based minimum inhibitory concentration analysis confirmed resistance to amoxicillin (>32 μg/mL), enrofloxacin (>32 μg/mL), fosfomycin (>128 μg/mL), and neomycin (>32 μg/mL). The discovery of such strains is a cause for concern given thatcan be shared by companion animals and their human owners.
