    Abstract

    One highly multi-drug-resistant, mucus-producing and foul-smelling strain of Klebsiella ozaenae was isolated from a patient in the ICU of a Chinese tertiary hospital. MICs of several clinical antimicrobials against the strain were obtained using the Vitek-2 Compact System with AST-GN13 cards and resistance genes were evaluated by PCR and gene sequencing. The strain was resistant to most of the β-lactams and quinolones tested and carried several antibiotic resistance genes, including blaKPC-2, blaTEM-98, blaCTX-M-3, blaSHV-26 and qnrS. To our knowledge, this is the first report of β-lactam and quinolone resistance genes co-existing in a K. ozaenae strain in China.
