We identified the carbapenemase gene blaOXA-499, a variant of blaOXA-143 from a clinical isolate of Acinetobacter pittii for the first time. OXA-499 shared 93.1% amino acid identity with OXA-143 and the gene was located on the chromosome. By cloning the OXA-499 encoding gene into the pWH1266 vector and transforming into susceptible Acinetobacter spp, we were able to show that OXA-499 confers resistance to carbapenems.
