Five OXA-232 carbapenemase-producingKlebsiella pneumoniae isolates, belonging to the pandemic clone sequence type 15 (ST15), were isolated from neonates and coproducedbla CTX-M-15 andbla SHV-1 genes. All isolates were resistant to ertapenem (MICs of >32 μg/ml) and meropenem (MICs of 4 to 8 μg/ml) and susceptible or intermediate to imipenem (MICs of 1 to 2 μg/ml). Thebla OXA-232 gene was located on a ColE-type transformable plasmid of 6,141 bp. To the best of our knowledge, this is the first report of OXA-232 carbapenemase among clinical isolates in China.
