Abstract
An IMP-4-producing Acinetobacter pittii strain coproducing oxacillinases was isolated from a leg wound of a 67-year-old female patient. Identification to the species level by rpoB and gyrB sequencing and multiplex-PCR-based analysis revealed that the isolate was A. pittii. Whole-genome sequencing of this A. pittii isolate determined the presence of blaOXA-96, blaCARB-2, and a novel blaOXA-421 gene. The position of this novel blaOXA-421 gene was similar to that of blaOXA-51 in A. baumannii, downstream of the phosphinothricin N-acetyltransferase gene and upstream of fxsA in the chromosome. This A. pittii isolate was found to belong to sequence type 119 (ST119). Here, we report the first isolation of IMP-4-producing A. pittii ST119 with a novel blaOXA-421 gene from a patient in Australia and characterize its draft genome.
