Emergence of carbapenem-resistant Acinetobacter pittii carrying the blaOXA-72 gene in the Amazon region, Brazil.

We sought to characterize the genetic context of blaOXA-72 gene in a carbapenem-resistant Acinetobacter pittii strain recovered from a hospitalized patient from Belém, North Brazil, in the Amazon region. We found that the blaOXA-72 gene was carried by a small plasmid, pIEC338SCox, that is 10,498 bp. The gene is flanked by XerC/XerD-like recombinase sites, which suggests that this gene was acquired onto this plasmid by recombination.
