Abstract
We present here the first report of an OXA-181-producing Klebsiella pneumoniae isolated from the fecal specimen of a patient in China. The OXA-181-encoding gene bla (OXA-181) was located on a 51 kb IncX3-type plasmid. Conjugation assay and whole-genome sequencing analysis revealed that this transferrable plasmid in the K. pneumoniae isolate might have originated from Escherichia coli and have the potential to mediate the spread of bla (OXA-181).
