Abstract
Metallo-β-lactamase (MBL)-producing Acinetobacter lwoffii was isolated from two dogs with pyoderma, a dog with subcutaneous abscess, and a cat with cystitis admitted to an animal hospital between May and August, 2011. All MBL-producing A. lwoffii isolates were resistant to ampicillin, piperacillin, amoxicillin-clavulanic acid, cefazolin, cefotiam, and imipenem; and were susceptible to minocycline and amikacin. Because MBL-producing bacteria has been recognized as a public health problem, veterinary staff at animal hospitals should be concerned about possible infections of dogs and cats with MBL-producing bacteria, including Acinetobacter.
